Greetings and salutations, Welcome to the Guitar C.P.R. Channel! Here I am going to try to give you a sampling of the type of work that comes through my busy little shop in West Virginia on a daily basis. We will be looking at guitar and amp repairs, along with some DIY fails. While the intent is not "How to" videos, there will be quick tips and other information I hope you can find useful. I hope you enjoy it.
I don't know really how a company like Fender could come out with something so bad... thanks for the video... never felt right to use it... and its not practical at all...
Martin has added the same type of much smaller wrench in the pricey tool kit for their new bolt on/shimable neck on the new SC line. Progress..... Thanks for watching.
Question please. When i pull the ating to play , the string touches the pick up metal parts and so it makes a pop sort of like electric pop noise . I have also notice with other guitars with same pick ups . I like to pull to play the strings how do i fix that , can i put like a piece of tape on the pick ups so it wont make contact
Either lower the pickups or do not push the string down against the pickup. Or lighten up with your right hand. Bottom line, the string should not hit the pickup at all.
Cost varies over various model revisions, does it need tube sockets? Do I need to make a tube retainer? Can the tubes be re-used safely and reliably? Prices for parts vary ( prices change nearly by every order, except the transformers Mercury has remained consistent for quite some time ) due to supply and flat out price gouging in some cases before the come in my door. Do we need a new speaker? Has it blown up, been on fire, or butchered by some hack? Highest price so far was around $600. not including a speaker.
I got a 50 year old story for you. 🤣 When I was about 5 years old we had a black & white TV that in order to adjust the vertical hold (which needed adjusting all the time) you had to insert a 12 inch long screw driver to adjust it... But don't slip as it would zap you big time! 🤣 I hated that TV!
The worst shock I ever got was in my very early days. The most convenient place for me to practice at the kitchen table. There was an outlet for my little LINE OPPERATED power transformerless amplifier just behind the chair at the end of the table, and I could lay my instruction book on the table. Sounds like a good plan right? All was well until I put my right palm against the side of my forehead and rested my elbow on the Gas range with electric clock.....of course I still had my left hand on the strings of the guitar. I remember seeing a blue flash, internal of course , as the ground on the stove collided with the voltage present on the ground of the amp. Which naturally passed through the side of my head most likely across my optical nerves to my left hand. I never did that again. Also learned do not play barefoot on concrete with the same amp. :) Kids these days don't know what they are missing.
@@guitarc.p.r.9675 oh shit! That had to hurt! I can kinda relate to that internal shock. I have to get neck injections for some pinched nerves... One time the doc hit a nerve with the needle and it felt like I was getting hit with a 220v line. That hurt like a biotch!
Once I saw the head amp tech at the store I worked at as a guitar guy take roughly 750 volts ac. I was doing some of the amp work and had an Ampeg V22 power transformer unhooked to check out. I had the ac on and ready to test when he came in the door. As he took off his jacket he asked what I was into, I replied I was about to check voltages on this transformer. He spun around with an "I'll do it!" before I could say anything he picked up the meter leads in each hand and latched onto the B+. It quickly knocked him backwards onto the stairs behind us. I asked if he was alright, he was a little pale, and shook. He said Yeah, but it felt like someone was hitting him in the chest with a baseball bat. After a cigarette and some coffee he was fine fortunately. He stopped in to see me last year, Had not seen him for about 30 yrs. Fine and doing well. We laughed about us both still being at it.
Can I get a list of the upgrades to take to my amp tech I would send it to you but I’m up here in Canada It would be appreciated especially the cap and tube upgrades
It was playable. Plus in this case it was a commodity for the current owner. He was an antique store owner who had made a bad investment. Refret was not an option, as original and lowest cost to repair was paramount. I would have had no problem refretting it, however to do it properly would have meant refinishing the fingerboard. All the lacquered boards are more difficult to repair. In this case the frets also need to be removed from the side, not the top. The finish piled up on the sides of, and soaked in under the frets does not make it any easier. If I had my choice it would have been refretted and an aged refin on the finger board. Thanks for checking out the video.
That same style of tubular flat apring material was also used as shielding inside late 1950s tube hifi equipment such as Scott and Fisher, to bring the AC wires up to the front panel to the on off switch without radiating hum into the preamp. I'm older than dirt but I never actually saw that stuff for sale anywhere and I have to wonder where the manufacturers got it from because it almost looks like something that was left over from turning metal on a lathe! I believe I also saw actual round wire springs used for the same purpose in some audio equipment from back then. The one caveat is that some alloys of spring steel cannot be soldered to.
I’ve been a customer of Charlie’s since 1998 when I was 20. I absolutely love his videos. Wouldn’t never take my amp or guitar anywhere Else ever. He’s simply the best ever to do this!! He takes a good guitar and amp and makes it great!! I’m so appreciative of him and his work!!
I like your channel.. a lot. Sometimes Marshall (Ok, and Fender, yes, and Vox) must use young graduates for their amp design. But even in the face of overwhelming evidence, they persist with stupidity. A classic example is not knowing how to use X- or Y-class safety capacitors. You explained it very well.
Thanks for the comment. I take a LOT of grief from know-it-all viewers. I have backed way off the videos for this reason. I have decided to resume on a very limited basis. It takes a lot of time to provide free information to many who seem to believe they are entitled to it, or choose to argue facts. This video in particular was done simply to point out the reason for changing this capacitor. If you have not already check out some of the comments. Thanks again, I appreciate it.
@@guitarc.p.r.9675 I am right with you. In one of my videos, a commenter said he would never bring an amp to me because I passed my coffee over the open amp. Hilarious. Could you imagine doing work for a guy who's criteria for choosing a Tech is his coffee etiquette? As you say, recording and editing is a huge amount of unpaid hours. Most of the Techs I know all say the same thing about Trolls. I hope you continue. I like your work.
No, I meant 1/4". They fit very tightly. 5/16" snaps in easier but I prefer the smaller size. E-clips are measured by inside diameter. 1/2" is useless here.
The teeth on the washers are pressed both directions, so it grips on both sides. The washer goes between the part ie; potentiometer, jack or switch and the surface it is bolted to whether it be pickguard, control plate, or body.
LOL,,,, the play nice thing just happened in the early days of the video, and it is mentioned in the 100k view video. It seems to be amusing to many. Also seemed like a good opportunity to say goodbye to an old customer and friend. Thanks for checking out the channel.
1. Is it a pickup cover wrapped in copper foil or the upper and lower bobbin? 2. Is there a hot and ground wire connected to it or just the ground wire only?
What plate are you speaking of sir? If you mean the pickguard I did, it just was not shown. If you mean the control plate, well it is metal already and is grounded.
Love the tone I get from my standard strat with ‘54 custom shop pups. How much tone would I lose doing this? I know that’s perhaps very subjective. The noise does bother me at times though it is not consistent in the amount of noise.
I found something very similar in the Netherlands. But without the pick up and very roughed up. How rare are these guitars? And does anyone know if i could find the original pick up somewhere
cool video Boss Thanks. I can't really explain why except I do love Teiscos' I have 3 set up and play nice. I also have collected a Trove of Teisco parts & pieces pickups; pick guards' bridges and so on. I enjoy restricting these old babies.. So much nostalgia & memories attached to this type of guitar.
Sadly, most did not have this knowledge over 20 yrs ago when the 2000s were born. Most of the amps failed after years of use. Plus, it was their flagship amp. People were impressed by them and they were put on stages all over the world. They had to be good, they were a Marshall!
Great restoration job,,,,,,,,,however being a long time player I'd remove the covers as they totally get in the way. I know Marcus Miller uses em but 99% of players can't stand covers. You really did a good thing not refinishing neck/body.
There's a quite similar one in my basement at this moment. Different sunburst, pickguard and pickup but other than that, same guitar. One of my daughter's old boyfriends who wanted to get into guitar repair left it here years ago. Needs wired up. My first was a Kay Speed Demon, single pickup, bought in '66 from a J.C. Penney catalog. There was nothing on the headstock so for decades I never really knew what it was. Sold it to a friend in '69 when I bought a Kalamazoo KG2A (which I still have). Ran into another Speed Demon in a shop a couple years ago, only it was $600, not the $29.95 I paid. I swear my hand recognized the neck shape when I picked it up. And yeah, I want one back.
I know what you mean, I was trying not to channel CCR, BTO, Brownsville Station, and a lot of stuff that just seemed to come back with that neck in my hand. :) The owner even mentioned giving it to me it it had my name label inside. I knew it was not mine, it had some pick wear through the plating into the brass pickguard. Glad you enjoyed it.
Ffs ive been spending $ on colour matching when i could hsve done this.... damn... never thought of that.... just used thic trick to fix a horrendous paint chip on a dime razorback. Looks mint now without any idea it was restored. Thanks for the repair life hack
I can think of quite a few classic amp designs that have this problem to some degree, screen voltage equivalent or in many cases exceeding the plate. Crank it up, and of course we're going to, and the screen starts doing the job of the plate...well at least for a little while!
Yep, see it quite a bit. Just in the last couple weeks I dealt with pretty much the same issue in a Marshall Mercury, Ampeg B-25 and a few others. Sorry you had to wade through that video it is an old one of quite poor quality.
@@guitarc.p.r.9675 not at all Charlie! Ive taken some things to you over the years and every time I've been in your shop I always thought to myself, Man I'd just like to hang out in here all day watching and listening to this dude and learning about this stuff! Then I would think about what a pain in the ass i probably would have been! Hey Charlie whats this? Whats that thing for ? Hey Charlie how's this work? 😆 I tell you tho in the pre internet days when i was trying to learn about this stuff but there weren't many resources, to go into your shop and talk to you was like visiting a wizard or something.
I have a set of 57/62 set on my strat. All pickups are the same meaning all have the same specs and polarity and wound. So there is no hum cancelling in ANY position. Will a Dummy coil help reduce the noise considerably?
Short answer is Yes. But.... I have considered taking this video down due to arguments over its usefulness. Another reason I have not been posting videos, because everyone has an opinion and is an expert on all subjects. It works, it has a couple drawbacks, well, because nothing is perfect. However, I have done this for years with a lot of happy owners. It is not a one size fits all magic bullet, and it takes a bit of knowledge to achieve the best results.
@@guitarc.p.r.9675 I understand. But I'd rather listen to people who actually applied what they learned like you. That is why I raised my question. I will see if it will help installing a dummy coil. The original pickup on my strat might do the trick.
You have to use an empty coil with no magnets or iron load. The plastic molded pickups Fender has used work well. You can slide the magnets out. That is exactly what Fender did in the Japanese made Strats in the early 80's. For some reason it was not accepted well.
Remove the from the molded plastic bobbins only. The magnets hold the bobbins together, and the magnet wire is wrapped directly around the magnets. Just in case you did not know.
I don't know if you noticed but the bass string is not following the neck very well. The space from the edge of the finger board to the string is growing quite considerably as you go up.
Sharp eye, but I reviewed the video to check what you mentioned. The strings lined up perfectly, I would not have gone through all that to leave an alignment issue. What you are seeing is referred to by one of my friends as an optical disillusion. I have caught this in other videos and changed angles to show that things are lined up. Videoing from a side angle of slightly above 50 degrees alone makes the strings look further from the fingerboard edge, and closer on the other side. Looking from the bass side and adding in the rise of the strings toward the bridge gives the impression that the strings lay farther from the edge as you move up the neck. Given the quick look, and the factors mentioned above, I can see why you would think that.
It's been said that an agreement Jim Marshall signed took away his freedom to build and design anything he wanted in a Marshall, so they started Park so it would be truly his company like Marshall was before.
Quite the proper business man. He did the same with Kitchen NARB, and Big M. Then there were the mail order specialties like the Marshall Mercury and Capri.
Great video! I've been intrigued by the Park 75 for years. Aspen Pitman (originator of Groove Tubes) has, or had, a red non-trem head that he says may be his best sounding "Marshall". This amp looks terrible inside, but if you were going to make it look nice you'd have been in there for a month.
Aspen, Rick and I discussed that Park amp. The original GT guys were family to me, Even though I was on the East Coast. Yes, that Park has some shoddy wiring going on. Personally, if it had been mine there would have been a lot of things done that were not.
Hi thanks for the video, i have a problem with my bias circuit. For some reason im getting -6 vdc on the ouput of the bias. Tried different x class caps but havent tried a normal couplong cap yet. Any ideas? Havent tested the electrolytic caps yet just tested thr resistors. Thanks in advance
Forget about the class x caps. Use a 630v Xicon. Check D1, and the caps. That is a very low voltage. I am betting a cap is shorted. But that is just a guess.
Thanks for the reply, i did one thing at a time. First replaced the cap with a coupling, was doing the same thing, then the diode. It was the diode!! Tested fine on the multimeter but changed it anyway and amp back up and running. Thanks so much for your help.
I replaced the diode with a 4007, however it was a secondhand working, I didn't have a new one to hand, so I installed a uf5408. I love used these diodes in previous diy builds. Do you have any concerns about using this diode in a bias circuit, I'm interested in what you think.
