Johan you are getting better and better at this. Looking forward to the next 30 years’ worth of videos from you. I like the seismic activity in the knob cam.
The bass model was a beast. I loved the 1986. I have spent a lot of time building bass, lead JTM45 models and transitions with SS vs tube rectifiers, etc. One thing to note are power transformer voltages, etc. Everything makes a difference...some more than others. Once you start messing with cathode bypass caps, and coupling caps, filtering transformer voltages, you will find one model will be a Goldilocks version, (this one is JUST RIIGHT). Great vid.
Awesome! I have a 1986 bass version from '68 (similar circuit I believe) and always wondered what a good comparison with a 1987 lead would sound like. Thanks for making all of the great Marshall videos!
Basically a super bass can still cook when cranked but if you want a good clean and fuller edge of breakup it will deliver a little better than a lead circuit. The lead circuit will shine for tighter downpicking and that extra 5% fire.
Thank you so much! I have both of these but from '69. My 1987 is plexi planeled with the black paddle switches. The 1986 is metal paneled with chrome switches same as my 1987 from '71. I'm sure those Daly caps are OK in your 1986. Mine has those too but are being replaced today. Love your channel // Matt.
Thanks for making this video Johan. I recently built a custom 69 Plexi Lead 50 watt and I can certainly hear the same vibe as the 1987 in my amp. I’m totally in love with my Plexi! It’s such an amazing tone and that crunch tone from a Plexi is unparalleled I think! Have an amazing day.
Enjoyed the demo of the wide palette of Marshalls Amp tones, and your thorough and pragmatic method. Both sounded huge. I preferred the brightness of the 1987, but that made me wonder how both Amps would sound when using a guitar with Single Coil pickups. I was hoping you'd have a sound sample or two with those. I bet the Bass version would have seemed like a different beast. Subscribed, Thanks
"...really interesting comparison...". I could not agree more. I love these in-depth videos, thanks a lot Johan! I need to see this video multiple times.
Was expecting Bass to sound sweeter in isolation and Lead to have that cut thru harsh tone. But Lead sounded way fuller and richer. Bass sounded like missing the meaty guitar frequencies. Great video.
It was very interesting to hear a Lead and a Bass side-by-side like that, and to see a little of what makes them tick. Thanks for posting this comparison. Well done. I think any reasonably competent rock player could get great tone out of either amp. Any differences between them or weakness of one vs. the other could easily be compensated for with pedals and/or speaker cabinet selection. Of course, the ideal would be a two-guitar band with one of each model... As to which _I_ would prefer to own? I think the 1986 Bass. If it's a bit too deep in the low end and conflicts with the bass or kick drum or whatever, that can easily be dealt with by a little knob-twisting. But it seems to be naturally resistant to producing ice-picky, fizzy sounds. I think that might be more versatile while still sounding great.
Throughout the video I kept liking different amps depending on how you set them .At the end the lead for me by a short half head pipped at the post ! Great videos, enjoy watching them
I wish they had an amp group they named 'Rhythm' , as opposed to just 'Lead' and 'Bass'. That joke aside, this is a great video - tells me a lot about the classic Marshall amps and their characteristics - thank you. I tend to subscribe to the notion that the Bass amp tends to work really well for clean/slightly overdriven sounds, while the Lead definitely has that crunch that many love. I also found that the more pronounced Gain stage makes for more soloing choices on the Lead amp. Be interesting how the 100 W versions compare?
Thanks! ;-) We’ll do the Super Lead/Bass too soon. I did a part of that one hear as well: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dvzYTZXIKeg.html
There was a reason players of the day had their Bass models modified to Super Lead specs. Surely it's subjective. But my vote is JMP Super Lead. Any replica by Germino Suhr or other of a non master volume JMP SL and buy a load box...so you can crank without the cops beating down your door.
I saw the dispute about capacitors in the file and I do agree : differents capacitors have different tonality. And when talking about Orange drop you have to point out the model. An OD715 is very different from a 225P or 6PS. Differents materials and building. 225P are polyester like the Mullard and could be not so far tonaly speaking.
Interesting comparison, and perfect work as usual. Great the comparison of the circuits. Strange, that ODs have been used in the Lead version. I very much hear my TAD JTM in the Bass version
The lead is like a tweed fender and the bass is REALLY like a tweed fender.. Marshall wasn't a brand of it own until the mid 70s with cascading gain stages. People always fully admit "oh the JTM45" was just a bassman rehoused" do they think there were any large differences during the plexi era?? a quick trip to SoloDallas will clear that up mighty fast..
Interesting video, I had both way back in the dim and distant past,.. couldn't get on with the super lead at all... in the room with it....found it ice picky bright. I was using a tube screamer and graphic eq for boost at the front though. In this recording I probably prefer the super lead overall.
Johan could we please hear a demo of the 1986? I have always wanted you to demo one! Just to add to the vintage amps recordings library that you have unconsciously created lol There very seldom quality demos of the 1986 model
@@JohanSegeborn Oh no I meant like a separate video, likt the past vintage amps series where you set the amp to settings you liked and just jammed some riff
Funny thing is that us freaks tend to think that the ´Mustard caps´ like in the Bass version are the holy grail of caps for a Marshall. The Orange drops are normally used for quality Fender type builds, and is thought of as being brighter.
Awesome comparison once again Johan… I own a 1959HW super lead which I love, but I must admit I’ve always been intrigued to the super bass dry and deep tone. Also, that Les Paul you are using just sounds amazing… can you tell me which pickup you are using in the bridge? Cheers
To me, the Lead had better clean-ish sounds, and had more clarity where as the bass had better crunch sounds. But I bet both of them would sound Amazing together.
1986 bass is certainly more musical to my ears. the1987 is shrill and lacks some mid complexity for my taste, in any setting. i have the 1964 lead and bass 50watt model from 1974 and the slp1959 reissue 100watt from 1993. they have exactly the same differences that the 1986 bass and 1987 lead have in this video. i prefer my 1964 over my 1959 and your 1986 over your 1987, 9 out of 10 times! but i absolutely agree with all your comments. try putting the pedal output of the original guvnor pedal to high input 1 and the loop output of the guvnor (with a mono cable) to high input 2 of the 1987 with your volume 1 on 7 and your volume 2 on 8 and your treble knob between 0 and 6. set presence and mid according to taste and keep your bass as low as your channel 1 requires for bright but full enough tone. the pedal off is the 1 bright channel and the pedal on is the distortion of the guvnor into channel 2. set guvnor with full level, treble and mid on 7, bass on 3 and gain on 7 or 8 at the most. tell me if you like the cleaner brighter and more dynamic channel 1 and the fatter heavier and more flat out distorted channel 2, at the flick of the guvnor pedal s switch! use a humbucker in the bridge position for higher gain and play with your guitar volume knob on the non distorted sound with the guvnor off. if you play with low output single coils keep your guitar volume and tone control a bit down if the sound is to shrill. with humbuckers you can use a boss ge-7 after the output of the guvnor and into channel 1 for a cleaner sound. set the ge-7 with less gain on than off. if you want higher and more cutting gain from your 1986 bass amp, just use any kind of treble booster in the high channel 1 input of your amp. this was a really great video!!!!!!!!!!!! johan, thanx a lot!!!!!!!!!!!! greetings from athens greece
I use the bottom left input on my stock 71 1987. I turn the bright vol up to 6 just where the bright cap starts to lose it’s effect but if I plugged into the top left it would be a little too gainy for my base tone, but the bottom input is perfect. Another bonus is that it’s 6db quieter so I don’t have to cut as many db’s on my Hotplate.
That bass amp roars . Now we know why Hendrix Plug his strat in to jack Bruce's bass amp. When he blew Eric away More balls with a single coil. Who give Jimi that advice. He was fresh from the states with no knowledge of Marshall amps at that point...
Yeah good point. I'm leaning towards the Bass amp . I play super strats think It would cut through. Used TSL in the past live. Gain channel p 8 b 7 m7 t5 Ultra gain for leads. Cut through a treat Still sounded nice & thick. Love your vids . Thanks.. the UK...
@@JohanSegeborn Hi Johan Following on my Hendrix Comment..just found out When Jimi got here UK the first band he jammed with before Cream was Brian Auger and the Trinity...they had a marshall stack. Jimi Plugged in and turned every control to 10 Wailed feed back & steamed into Hey Joe. Chas Chandler took him there. Catch ya later. Love your channel..
Oh - and another suggestion. Your love for things "Americana" is obvious and makes someone like me feel good about being American. The fun stuff especially! Muscle cars, Coca-Cola, Gentleman Jack, Rock n' Roll, Gibson and Fender, Elvis, California dreaming, Summer babes. You should come over here more and spend time. Here's my suggestion though - you need to start incorporating the word "man" into your conversations and presentations! Like - Hey man. Check this out. We're gonna be playing this boss Marshall Plexi LEAD, man. And it's gonna be alright. :)
How close can a 1987 get to a 1986 tone wise? I noticed the tones from low input vol 1 of the 1987 sounded VERY similar to the high input vol 1 of the 1986. It's just a very short example of each, but I jumped back and forth the best I could, seemed really close.
Not sure if the 1986 model(bass) has shared cathode in your test Early lead and bass models and later 2100 combo amps with shared cathode sound particularly nice with strat and 6402 cones open back
I have a Marshall Lead & Bass 50 watt combo Made in 1975 by Jeff the label on the inside says, I have been told the Lead part is 1987 & the bass is 1986 circuits, anyone have any knowledge of this this amp. it,s the same amp Paul Weller uses.
you cant be serious, one has an output transformer from a later period and coupling caps that sound a lot more modern, you simply cant compare these two amps as one is so extensively modded . the correct way to do this sort of comparison is to find two unmodded amps, and use the same glass, otherwise its an utter waste of time.
I don’t think the brand of caps are that important actually, we can compare mustards, orange drops and affordable current no name caps to find out here on the channel. You’re right about the OT though, thanks for bringing it to my attention, it’s late JMP rather than 800 though?
@@JohanSegeborn Johan you're relentless, a true tone hound, I'm a devoted fan, however I have to point it out to you, mustard caps vs orange drops is a big deal, tonally, the orange ones are brighter with more bass, a lot more actually, these variances cause a perceived mid scoop effect. They pass a lot more bandwidth. The o/t is also a big deal, there is variation within batches of vintage o/t's due to less efficient winding methods that cause different winding patterns, this is the reason 10 plexis with sequential serial numbers will sound different. To have one made years later...
