Should You Adjust Your Humbucker Screws 

Adjusting pickup height will determine overall gross frequency response and output, and then adjusting individual screws adjusts the balance in output between strings to compensate for the different thicknesses of the core wire. I'm always amazed at musicians who reject a pickup without adjusting the pickup in the guitar.

You can measure this any way you want but I can deffinitely hear a higher volume from the strings I screw the poles closer to. Usually end up with two three pole stairs from the low E to the D that's the closest to the string and the G, who is the furthest to the high E. I do this completely by ear. In soapbars I set them at the same string distance (fretting the string in the last fret, 2.5mm from the low E and 2mm, then testing overall volume ballance between pickups and making minor adjustments and lastly setting each pickup's poles to match the string ballance). You can 100% tell the closer you have the pole to the string it sounds louder. I guess it could change if the screw is way outside the bobbin which should not be necessary at all to balance them out.

Love how YOU tell me what I should and shouldnt do with MY guitar.

This actually explains pretty well why I like having them slightly raised. I find my burstbucker 2/3 combo to be a bit muddy and a bit hot on the output. Raising the polepieces up a few turns, lowering the pickup slightly, gives me a bit less output, a little more clarity, while still being VERY different from my tele and strat.

For a proper experiment, measure the magnetic field at string level on a mounted pick-up with slug up or down. The string will provide a stable reference distance from the magnet in the pick-up.

The way the probe tip was positioned . . . Those readings absolutely made sense . . . However, I like to see the readings from a static probe position . . . let say 5mm . . . to emulate the string distance from bobbin . . . from the two screw heights . . . I suspect that these will read differently . . .

I say trust your ears. If you like the sound of your guitar then leave it as is. If you are thinking of swapping pickups I suggest to play with the screws as you might get what you were looking for. Worse case scenario is that you just put the screws back where they were and you can make a choice from there. I've had pickups that basically "woke up" from factory setting with just a few minutes of playing with the screw. To my ear the pickup gets clearer, less muddy. I get a bit more twang and jangle so that suits me fine. I learned this from the screws of Filtertron pickups being pretty high off of the body of the pickups. Again, trust your ears.😉👍✨

They were designed so well that theyre still used today and nobody has been able to improve them, even active pickups, some like em but most want the standard humbucker. Has it been 75 years now? Thats really something, there may never be an improvement to the original design. People keep trying but not yet anyway

I adjust the screws both to get even volume between the strings and to get more of a single coil sound from a humbucker.

I have ephiphone riviera with p90’s and I always had the issue with the 6th spring being too loud, took to my guitar guy, and he adjusted the screws on the pick up’s and the magic happened, now plays like a champ, and is perfectly balance

I adjusted the one humbucker screw up to bring it closer to the thin E-string, and I *could hear* that the sound for that one string got louder... 🤣🤣🤣 Thank you so much! I loved this!

Opening is genius. Well played

Ok here's verbatim from horses mouth, Seth Lover from an interview with S. Duncan in 1975: Q: "We talked about the addition of adjustable poles pieces; would that change the sound any, the magnetic field disbursed through the bobbin? A: On the humbucker the adjustable pole piece extends out the bottom. If you had a magnet that was quite weak you could absorb some of the energy, depends on how far through that screw was, because it’s going to absorb some of the energy there. But as a rule, with a good magnet there wasn’t too much. Q:What was the reason for having adjustable pole pieces? Was it for a better balance between string? A: Yes, It would give you a better balance but it was also a selling point. So, again, it depends, nothing is set in stone (or Seth in stone). It's an easy try, retractable, try it and if you can hear changes it does make a difference, it you can't hear any changes screw them back down again, no harder than that. You don't ruin your pickups. Takes less that 4-5 minutes.

Bass side lowered with poles raised, treble side raised with flush poles. Makes for a thicker sound on the high strings and a bit more articulation on the low strings. Just my preference.

That's very interesting Dylan that the gauss reduces as the pole is screwed out! Normally when I adjust humbuckers, I have them a little lower on the bass side, then start adjusting the pole pieces from there. But to tell the truth, it's pretty hard to tell the difference in output. I just adjust them until all strings sound even'ish.

I have learned to surround myself with people who are smarter than me. Since all my humbuckers say Dylan on them, I leave them how you send them to me. If the screws were supposed to be up you would send them to me like that. Thanks for sharing. Have a blessed day

The way I set them up is I turn off the amp, effects, eq’s and everything in my multieffect processor or DAW and use the input meter of the signal on each string. I then raise or lower each side of the pickup so that I can get the most even and similar signal on each string using the input meter. Usually the high E and D are a little off. I have found that raising the screw on those two helps further even the signal. I like it that way.

This is quite confusing because when I recently bought a new guitar with humbuckers, especially plain G was very loud compared to wound D when all polepieces were at same height, and I could get it very much to balance by adjusting those screws. 🤓 P.S. I checked what I in fact did, and I just turned G string polepieces 2 mm down.

Yes, YOU do make a difference. All the differences that are watching that don't make a difference by not letting their difference be known, are the ones that can't complain when the facts don't fit. Great video. I've not had a need to mess with my pick ups. I now know something new. Thanks for the information.

Physicist explanation here: I think what is actually happening is that the screw being higher just makes the gauss meter further away from the bar magnet at the bottom of the pickup, resulting in a lower field reading. Still though shows that the screws have no effect on the field strength based on the their height. Great video as always!

I adjust hb screws for balance, with the one for the third string below flush. I like having a balanced sound, with no string dominating. I turn the neck pickup around so that the pole pieces are on the bridge side to make it brighter.

That guilt trip section though 🤣🤣🤣 puppy and a cat too!!

I adjust the height of the pickup to taste. I then use the screws, to adjust the loudness per string to get it even. Works for me.

Thank you so much for this, Dylan. I unfortunately read on forums about this when I was trying to get the mud out of my P90 neck pickup in my LP special. Dropping the pickup down and raising the pole pieces was supposed to make the treble stronger and drop the mud out a little. It didn't do anything for me or at least nothing positive that I could hear. I got so frustrated with it that I just returned the screws to their normal height and dealt with it the mud until another solution came along.. At least now I know that it was bullshit all along and will never ever play that game again, LOL . Once again, you share great knowledge with those of us who really need and want it!

Dylan, shouldn't it make sense to install screws of different lengths in each slot, that would have the affect of compensating for differences in common string outputs?

I started adjusting the pole screws based on the neck radius. I find it give more clarity but who knows. Eg. Outer- flat middles- half turn inners-full turn. Saw this ‘tip/trick’ on a page for a boutique pickup builder. Obviously adjusting the entire pickup height to string accordingly after, where I’ve always enjoyed the Gibson recommendation for heights

The segment video about hitting the subscribe button is hilarious. That sense of humor is why I became a subscriber years ago

The screws DO adjust the string balance, just like they do on a p-90. They are not there just for marketing. Most of Fender’s original pickups had staggered pole pieces to compensate for the differences in output from one string to another. When Lover designed the wide range humbucker for Fender, he again included height adjustment screws. When Seth Lover specified his ideal humbucker for Seymour Duncan, he once again included height adjustment screws. While it was his opinion that Gibson only wanted the screws for marketing, I would assume they wanted them for the same reason they had them on the p-90: to adjust string balance. Seth Lover did not play guitar, so he probably didn’t understand the importance of this feature immediately, being more concerned with the hum canceling aspect.

lowering pickup into the body then raising the screws up makes my les pauls neck up less muddy gives it more like tele style punch

I get what you are saying. But I'm not 100% convinced that the Gauss meter reading translates directly to impact. For example, even if the field is weaker at the top of the screw, it is also true that this weaker field is closer to the string. And I think electromagnetic fields tend to weaken in proportion to the cube of the distance. To me, the only way to really assess impact is to measure the signal the PU produces with the screws at different heights, in a controlled test where you can reliably reproduce the "string pluck" (I envisage some sort of "mechanical plucker"). Or measure the frequency spectrum of plucking all 6 strings and see how the spectrum changes after PU screw adjustments.

I have always tried to make these changes guided by my ears and how I think my guitar sounds better for me... I didn't know about these things before, but I found the bridge pickup sounded more punchy by raising the whole thing and lowering the poles, then I just moved some up or down depending on how I found the sound to my ears... And I'm pleased with it!

So a couple of thoughts. 1. Just because Seth Lover didn't add the screws because he felt they were important doesn't mean they aren't. Happy accidents happen all the time. 2. You say that the field gets weaker because it's pulling the scrw up out of the bobbin, but that's just one type of humbucker. On some DiMarzios for example, the screws extend well past the bottom of the bobbin, so when you adjust them the length still in the bobbin is the same. 3. As someone pointed out above, field strength does not weaken linearly in space, so a weaker field closer to the string may still produce a stronger signal. Personally, I either don't adjust them, or I adjust them slightly to follow the radius of the strings and fretboard, but I can hear the difference when I do.

Maybe it's just me, but I definitely hear a difference when adjusting the screws on a humbucker. I start with the high E polepiece screwed iin and evel with the top of the pickup at 3/32 away from the string. The low E is done the same, but 4/32 away from the bottom of the strings. The remaining strings are adjusted to match the radius or until I'm happy.

Hey Dylan. Would you please touch on the topic of ebow, could it possibly affect the polepieces in a negative way when used directly over the pickup?

Fascinating as usual! I like mine flat on the bridge and I raise the neck screws a few turns and lower the overall pickup. I find it makes the neck pickup less muddy. This makes sense now that I know how it works!

It's akin to people talking about wood and the fact was that Leo bought what was available and cheap. I've always just used it as it's sold.

Nice video and great explanation.

Dylan, great vid. Just for my info, what is the reading on one of the slugs?

I've experimented a lot with Pickup Body height, and Screw height on Humbuckers with Screw Pole Pieces. Both make a difference. I adjust the body height to get the basic sound I want, and then adjust the screws to get the balance between strings I want. It's critical to use your ears, and not be swayed by your eyes. I've had a couple Pickups where certain Screw Pole Pieces made the particular strings they were under unmanageably hot. No amount or raising or lowering the pole pieces alone or in combination with the other pole pieces or with the body height or changing string gauges would allow me to get a balanced volume across all of them. I also tried some different types of screws/materials in the offending locations, and learned a lot from doing that, but matching threads per inch and pitch was not easy. I looked up the screw types, and determined they were called "Filister Screws," before I decided to Mod the problematic Pole Pieces, just in case I needed to replace them. I got out the Dremel, and started grinding off a little of the bottom of the screws where the threads are, putting them back into the Pickup to test if it was making them adjustable into a range that I could get a balanced volume. I worked slowly and carefully. After a several tries, I achieved a workable volume balance within the range of adjusting those screws up and down. I ended up removing about 1-1.5 mm from the bottom of the screws. I wouldn't suggest anyone do this who doesn't have a good idea what they're doing. I had never read about anyone doing such a Mod, but it seemed to me like it could work, and if it didn't it was reversible for a small expense. Luckily, everything worked out, and that made two of my favorite Pickups work the way I wanted. YMMV

I guess the question is, does the screw’s closer proximity to the string make up for the loss in Gauss? Also, how does this apply to pickups with just one row of pole pieces, and no fixed slug coil, such as those dog-ear P-90s? I had a bass years ago with a DiMarzio P-Bass pickup, featuring individual screw pieces in a row, and raising one of them up individually definitely made a string louder.

I have adjusted the screws on previously dull sounding pickups and it helped some of them. Some were too far gone in the mud to clean up.

Thanks for the video! I wonder what would happen if you would remove the screws alltogether. Would that make the humbucker act more like a single coil? I think it would not be bucking the hum anymore but still function as a pickup but I never had the cocholes to actually try it out.

I never adjust those screws, but your explanation was completely opposite of what I would have expected; the more you know...

Very simple and informative, thank you! A question, I have long admired the MFD (allen wrench adjustable) pickup design. Do these same rules apply with them?

So all these years Ive been talking crap about my SGs Pickups and it was just the screws beeing to far out... THANK YOU SIR

Great discussion, I have always wondered how much difference it really made. I have played with adjusting those to help balance the individual string volume but never knew for sure what was actually happening.

What effect does the lowering of gauss have on voltage?? Does the closer proximity and thus theoretically more potential for absorbing vibration make up for the weaker magnetic field, i.e. will the resulting voltage be more, less, or unaffected by raising the screws??

Could this be why my 90's Strat, flat-pole pickups are my favorite? I think YES! lol

Great video! I never move the screws, always the whole pickup. Not for any specific reason... just never seemed necessary.

Would suggest measuring the field strength at the actual string height.

It made a gigantic difference on my guitar. Difference between sounding muffled and going out of tune all the time, to legitimately being one of my favorite pickups and never going out of tune. Definitely adjust your screws before trying to get some new pickups. Also, try stuff out and learn for yourself. That’s how these RU-vid guys learned. Too many people take a lot of this as concrete, and almost none of it is. Explore, have fun, play standing on your head if you want

I’ve been messing with my HSS strat pups for a long time trying to get the humbucker to balance more with the singles. I tried raising the pole pieces and lowering the pickup in the humbucker a few years ago, seemed to like the results and didn’t change it back. Makes sense now

I Never experiment with those screw but I had a jazz boxe that the previous owner raise the screw for the plain/top string. That guitar had a really nice string to string balance. If I ever find that a string is too loud or not loud enough in a set (like a wounded G string) i'll give it a try. I don't own a humbucker pickup at the moment. All fender single coil.

Well done. I've always left mine alone. I will and have adjusted the pickup height to address tonal issues/desires, but not the individual screws. PS- I'm a USCCA Instructor and IDPA S.O. I like your t-shirt. My main competition piece is a NH Custom.

Thanks mate , cool video

Thanks for the useful info man. Very informative

This is a great video. Really enjoyed it.

I have not ever adjusted the pole screws on any pickup. I do have a P90 guitar, but it is mounted into the body and has an adjustable height for the whole pickup. I have never found any need to adjust the pole screws.

The beauty of the current pedals and amps is that w can get the same (or at least extremely similar) tones than if we jack around with the screw heights.

D, another helpful and great video, thanks. question... why do you bother with using screws at all ? i was a little surprised you did not give us the gause measurement of the slug coil. thanks, steve

I have a PRS that noticeably had a drop in volume with the B string. I raised that pole piece and could hear the B string much better. I say all that to say that either I had a placebo effect or something in the magnetic field inhibited that screw, at that height, using that amp, from cutting through the mix of strings. Either way. Great video that makes great sense. Another guitar I changed was my White Falcon with filtertrons. It just sounded muddy and I couldn’t get the guitar to brighten up. I raised the pickup and the screws all the way up. Everything brightened up and it sounds great now. Final one was the wide range humbucker of a reissue fender where I raised the poles on one side and lowered the poles on the other. Cleared that pickup up too. Interestingly enough my actual 73 Tele Custom Wide Range needs no such adjustment to sound clear.

Reverse mounted pickups seem to make a difference to pinch harmonics. I find they happen a lot easier with a reverse mounted neck pickup than a correctly mounted one. Unless I've just suddenly learned how to do them correctly...

I set my pickups low in the rings and unscrew the screws a bit to a point where I like the sound best. I prefer bright pickups to warm pickups. I know that lower wound pickups tend to be weaker and also brighter than high-wound pickups. So it kind of makes sense to me that I would like the sound of raised screws, because even though it weakens the signal, I just really like that brighter, less warm sound. Great to know why that is. Thanks for the video!

The P90 history has the big difference in construction. The original had a bar magnet instead of poll pieces or screws, like a blade pickup, then when it got the bottom mounted bar magnets or staple magnets they went to screws with a quick stop for polls. I would love to see some one make them with a similar coil and see how the construction differences sound.

What are your thoughts on the concept that raising the screw height on say the neck pickup can make the tone brighter?

I sorta figured this out about 30 years ago playing with the poles on my JB pickup in my Kramer Nightswan. I just found it more balanced with them all screwed flush and raised the pickup. Throughout the years I always started gravitating towards blade and slug style, ie. My Bill and Becky Lawrence XL500 in my Hamer Californian. And some Seymour Duncan blackouts and Heavy metal Live wire etc. Really appreciate these videos your doing, I was wondering if you noticed faze issues with the pickups being way too close to the strings. I tried it and really didn't like the sound that close and the faze issue was noticeable to me. Again great content, Cheers!

Isn’t that the point? You can adjust your bass side so it’s not as muddy or screwing in your treble side if the tone is a bit too harsh? That’s what I’ve always done (the inverse adjustment). Especially if adjusting my pickup height didn’t do the trick. Then again my ears over the years have gone to hell so it just doesn’t matter as much anymore!

hei dylan,why you seting pickup hss height? for balancer output

So then why are all the pole pieces on my fender ultra at different heights? Mind you they are non adjustable slugs. Is that just cause single coil pickups are different than a humbucker?

Fantastic video! I have all of my pole pieces raised - but I shall experiment. I have a Gretsch Electromatic, and I'll experiment with them too. The neck doesn't like to be higher than flush with the body and that doesn't seem right to me. I've noticed that on some of Joe Bonamassa's some of the pole pieces are quite low, almost gone - I'm sure he tinkers too.

I've often thought about experimenting with the screws in my humbuckers. Without the necessary equipment to graph the changes, I couldn't see a benefit to it. Now that you've pointed out the history behind the screws, there's no point in adjusting them. The one's I have and the way I'm using them sound fine to me. What's interesting is, I've always wondered why all the screw slots were set in the exact same direction or in a pattern if minor adjustments made that big of a difference.

I raise the middle screws up to match the radius of the neck, thinking that would make them a little stronger, but as you just showed us, it does the opposite! Thanks for all the great info you give us.

Well, here is my personal experience. Many years ago, when I was much younger and I could only afford one guitar at a time (irrelevant but sets the scene 😎) I owned a Kay Thinline hollowbody guitar with P90 style pups (great tone, by the way) known as the Kleenex Box style as they had a plastic cover that looked like the Kleenex dispensers in hotels of the day!! It had a set of strings with a wound 3rd which I stuck with as I fitted a Bigsby rocker bridge with the bigsby style trem (probably licenced in those days) which was compensated for a wound 3rd. This set up resulted in large variation in volume from string to string with 1 and 3 being the weekest. The pole pieces had turret-like cross-slots in them, clearly to facilitate adjustment. Using these I was able to even out the volume of each string much like a compressor would but I didn't have access to such high level electronics back then (late 50s early 60s). So, it works counter intuitively to your measurements. Maybe the proximity effect outweighs the power of whatever you were measuring (I'm no expert) but the effect was very noticable. I have never felt the need to adjust any humbucker, by the way. I toyed with the idea of putting a modern adjustable saddle on but decided to go back to the original mahogany bridge and saddle. Great for jazz!

I try to get the "loudness" of my strings as even as possible. That may sound picky (pun intended), but I love to have control over how the instrument reacts to my playing, without having to memorize which string rings out louder and which weaker when I pick a note on it. Not all string sets are equal, so as soon as I find a specific set I like best on a respective guitar, I first adjust the pickups with their outer screws to give me the sound and volume ratio between high and low strings I prefer, and then fine-tune individual strings if necessary (more often than less). I always buy 2 identical spare sets min. and put 1 into the gig bag. In most cases the G screw goes in, and the D screw out a bit (from 1/2 to 1+1/2 turn) to have them at the same volume when I pick them with equal strength. In case I switch to another string set (gauge, material, brand, …) on that guitar, I always do the dynamics test again and adjust accordingly, because there is always a change.

So would you raise or lower the pole screws for a brighter tone? I could literally use my Les Paul neck pickup to play bass. Come to think of it, my Tele is the same. Got as much boom as a P-bass

I also had the wrong idea about raising the screw heads higher... Is there any way of manufacturing a pickup that gives an even output?

Very interesting Could you compare the value from Screw with the aligned slog in the same humbucker? (I mean let say, the first screw with the first slug.)

Neck pickup: high e and B poles raised about 3/32 inch above the cover. G flush or slightly below the cover. D raised slightly so that weaker string balances with the G string. A and low E flush or slightly below the cover. Entire pickup slanted so the high e is 3/32 inch below the string fretted at the highest fret. Bass side of pickup about 1/8 inch below the top of the mounting ring, but will vary depending on the neck-to-body angle of the guitar. Bridge pickup: high e, B and G as on the neck pickup. D raised so that the entire screw head protrudes from the cover. A and low E strings slightly lower than the D string. Pickup the same distance from high e string as for the neck pickup. Bass side of pickup a lot closer to the strings than the neck pickup, adjusted by ear so that the wound strings are in balance with the plain strings. Both pickups are on all the time. In fact, whenever one of my toggle switches starts acting up, I simply connect all three hot lugs so that the switch is inoperable and both pickups are always on. This setup sacrifices a little bit of output to create a balanced tone where the highs are very big and fat, but the wound strings are clean and tight, almost a single-coil sound. If you want to get some idea of the result, listen to Duane Allman’s bridge pickup tone on Live at Fillmore East. I’m not sure how Duane did it, but I’d guess that he adjusted his volume control quite a bit, turning it down when playing low notes and turning it up on the high notes. I’ve also heard that he was using bass amp heads towards the end of his life, as well as Fender 150 Rock and Roll strings, .010-.038. The relatively thick high strings and thinner wounds were an important part of his strong treble response. An important thing to note is that my setup works well with modern Les Paul wiring, but not very well with so-called 50s wiring. I’ve modified a couple of my guitars so that there is a master tone and a master volume, in addition to individual volume controls for each pickup. This makes volume changes a lot easier when blending the pickups at different volumes to color the tone towards one pickup or the other.

Well, Gibson in their "golden era" radiused the screws with the fingerboard. But you're talking less than a MM of height difference between the E strings and the D/G strings. So you're aren't losing the gauss that you would doing an extreme example as you showed. The fact is, that if you put a cover over the pickup, even as flat as you can get the bobbin inside the cover, people turn the screws a few MM's to poke out of the cover. So I guess "the holy grail PAF's" that everybody goes after had "weak" screw coils by application and design and that's the sound. That said, that could be the defining difference between a covered and non-covered pickup.

How about I adjust single coil screws?

Excited for this one. I always tinker with these but I always end up at the Kalamazoo method. It makes “sense.”

I usually adjust the screws higher when I want more clarity and less bass and gives an almost single coil tone

Good stuff Dylan, thankyou

Thank you for sharing I leave mine how they come

I've never liked your channel. But this is a good video. Thank you. I'm glad RU-vid algorithms sent it to me.

Thanks for the info, and for confirming something I first observed decades ago and always found counterintuitive. I adjust poll screws to modify the output balance across the six strings which, to my ears, is clearly a thing and something I've always been sensitive to. I play with a relatively clean tone and an unwound G string (I'm old enough to remember when "wound vs. unwound third" was a raging debate). I'm also fussy about the amount of percussive pick noise I get, especially while strumming, and will use the mount screws to adjust the overall pickup height. If you can disprove my perceptions, it would blow my mind but I'd be very interested!

Adjustment is necessary in some cases. If you've got ceramic magnets, thicker strings, and use open tunings -- if you don't adjust your pole pieces, a lot of your chords will sound like crap. If you have a pickup with no adjustable pole pieces, and the same thicker strings, ceramic magnets, etc., being a little creative with individual string height and overall pickup height can also compensate. Being that a lot of players use light strings and don't play a ton of full chords, pole piece adjustment may not be as crucial, but believe me, all my guitars have ceramic magnet pickups, and I play 50-12's, and pole piece adjustment is crucial. Otherwise, you get a string or two that drowns out the others, sticks out like a sore thumb, which really sucks musically and sonically. I also agree with the other poster who says that the gauss is probably better measured at string height, because even if there is less gauss at the head of the pole piece, the closer proximity to the string, and increased interaction with the string, will probably counteract the decreased gauss. And then you also have to take into consideration that at string height (especially if your pickup is more than a few millimeters from the strings -- some guitarists have their pickups set further away from the strings than others) any individual string is being 'seen' by more than one pole piece. So when you're adjusting pole pieces, it's really adjusting just one part of the whole magnetic field. If that makes any sense.

Hey Dylan. So when I was like 14 I had a really cheap epiphone Les Paul Jr, that had a humbucker instead of a P90. In my infinite wisdom as a 14 year old who just started learning how to play powerchords, I thought I could make my humbucker sound like a single coil by taking the screws out of the pickup. What was I actually doing to the signal by doing this?

After many years of working on guitars, I started messing with this out of curiosity. I matched radius with the strings on my PRS Mira. I like it. Maybe I was just turning down the middle strings. I’m going to fuck with it more. I want to see if I can affect string to string volume. I’d like to get a better balanced volume string to string.

Interesting video and well done. I think for more information, you can test all the pickup screws down with the meter test probe approximately at string height distance..... and then retest the same pickup with all the screws adjusted up (again with the test probe at about string height distance from the pickup). I would be curious to see what type results you get. Thanks for doing the video. Interesting stuff...Gave you a sub. Phil

Interesting stuff. I appreciate this video...its an aspect that I haven't seen much discussion about. I wonder if there's a significant difference between tube amps and modelers with respect to screw adjustments. I never messed with pickup screws with tube amps...like you, I adjusted pickup height and played. However, I do get worthwhile results in my modeling rig (I no longer own a tube amp so I can't compare them myself). So, in light of your video, I am interested in why I hear those changes...wound strings have better clarity and unwound get brighter when I raise the screw in relation to the slug. I wonder if the reason is that it is changing the interaction between the slug and screw coils, re: changing which of the two is gathering more energy from the string. It may be that I was thinking that raising the screw was making the screw coil brighter when, as you point out it is decreasing gauss, and thus emphasizing the slug? Does the type of magnet and amount of winds matter? I use A5 overwound bridge pickups, fwiw...how might a humbucker with A5 /5000/42 gauge wire versus another with A2/4000/42 differ on this subject? Another thought, and this might be idiotic (I acknowledge that I only know enough to be misguided LOL) but is there something going on with phasing? In the end, I can make the guitar sound better by adjusting the screws, and that is really the only bottom line for me.

Question: Is there a difference if the screw is in or out, but the same distance from the string?

Anyone know if Mr. Dylan has a video on the correct orientation of a orange cap install? I heard there's a right and wrong way to put in your caps.

Wow thanks man! I always thought the exact opposite but that totally makes sense that the further away from the body of the pickup the screw is the less powerful it'll be. Time to re-adjust some pickups! Man i wish i had youtube back when i started playing, even better ive got it when im 40! Lol

What is your opinion on the direction of the screw slot on the adjustable PU? I had a Certified Gibson Luthier, who I went to one time, tell me the slot heads had to be parallel to the direction as the strings. Sounds like a marketing gimmick to me.....

I had an Ibanez with muddy pickups. I lowered the pickups and raise the screws really high and all the sudden they sounded like PAFs. They sounded really good but it was some extreme adjustment to get them there. In that case it worked out.

On my gold top I adjusted the neck pick up down on the bottom 3 strings and raised the screws on the low e and a string because I was getting to much bass on my power chords. I found that by doing this I got a more even response across all the strings. But thats just me.

When I got my first electric guitar, even though I am not normally a take things apart type of guy, I did just that. I adjusted anything that could be adjusted other than the truss rod (that came later to practice for adjusting one on a different guitar) But yeah, I moved those screws all over, before finally putting them level. I later swapped out pickups on the guitar, and don’t mess with them It was fun, and I didn’t ruin it, but I did mess up the intonation

Here's a tip from an old guy. The two long screws that hold the pickup in the frame. Bend them very slightly in the middle. What happens the is, as you turn the screws up and down, the pickup will wobble. You then get the pickup where you want it and adjust those two screws so that both bobbins are exactly the same under the strings, Usually, the dummy bobbin is lower than the screw bobbin. YMMV, but it works for me.

What about Leo Fender’s G&L MFD pickups? I “think” they use a stationary sleeve with an adjustable inner screw for each pole. Would be interesting to see how an MFD pickup behaves in that same gauss test.
