The ORIGINAL Eric Clapton Blues Amp - 1964 Marshall JTM45 BLUESBREAKER (Repair, Analysis & Demo)
HTML-код
- Опубликовано: 15 сен 2021
- In this video, we'll look at a real historical HONEY of a guitar amplifier. This is NOT a reissue! This is an ORIGINAL 1964 Marshall JTM45 Super Tremolo Amplifier Model 1962, known affectionately as the "Bluesbreaker" after the John Mayall album "Blues Breakers", on which a young Eric Clapton played. It's always nice for me to see amps like this because so few of them exist, and also because so few of them exist in my part of the world.
The owner of this amp is also the owner of the Fender Champ I recently serviced. We sent the original speaker in that amp off for a recone at The Speaker Workshop due to a rubbing voice coil. While picking that amp up, he decided to bring along his Bluesbreaker, which has been sitting for over a year untouched, due to a badly punctured Celestion G12 T731 speaker, which apparently came originally in a Selmer amp? We are not sure. In this case, he wanted to avoid a recone if possible, so I'll show you how to fix a speaker puncture using a hot glue gun and we'll open up the amp and examine the guts. Then we'll plug it in and jam with some Glen Miller custom korina Gibson Futura and Flying V guitars.
This is the WORST speaker puncture I've ever attempted to fix using this hot glue method. If you DO need a recone on a vintage speaker, I highly recommend The Speaker Workshop in Fort Wayne, Indiana: bit.ly/RECONE

Hi. I signed up for the channel today. I'm passionate about tube amplifiers and today's video is sure to be special. I'm a big fan of Eric Clapton. Congratulations on your work. Greetings from Brazil. Rodrigo Bortoloti.
😍 we love Brasil 😍
Welcome to the best guitar channel on YT
I'm grateful to have you, Rodrigo. Welcome. There's beer in the fridge.
Bem vindo, finalmente um brasileiro nos comentários !!
Really great video guys! Greetings from an old bugger from the UK!
Get your beers and snacks ready for this one. This is an hour long amp geek out session!
i am ready! go
Some of the best greenback speakers I have ever owned had glued tears like this and they sounded amazing. I wouldnt recone it because the voice coil would be changed and the new cones and voice coil wouldn't sound as good in my opinion. Nothing wrong with a glued cone. Nothing at all.
You down around Hazard County? I thought Bo Duke walked in. HAHA! Them damn Duke boys are at it again. Man I'd love to own that amp.
I keep expecting to see that clip pop in from FastTimes “You can’t fix this thing Spiccoli!”
Awesome. I love these long videos
I'm a Marshall guy in the UK but do lots of others . I also design and build combos that Marshall should have made back then , convert Valvestates to tube , that would include Trainwrecks and Dirty Little Monsters of course but also add my own touches when building an EL34 out amp by chucking in an EF86 as a second preamp tube . Just restored a Hi Watt Custom 100 fitting new caps inside the old cans and swapping out a couple of other components . I'm now converting a Vox 67 Traveller Solid State to an AC4 type combo using as many original parts as possible . The cabinet is the same as the AC10 etc. The construction of the Marshall and Vox cabinets are similar in that the front baffle is one piece bolted in all around. A saw cut takes the grill cloth and tolex with a length of trim wedged in to finish so not that easy . It can be invisibly repaired from the front using a darning technique by using butterfly plasters to hold it in position . Probably the hardest job to do on this as the more time taken the better the results . The Mullard mustards are normally all good but I have the spare 0.22 uf ones swapped out with Spragues in your example . I use plain toilet tissue and Titebond water based glue to repair cones and inner tube rubber solution to repair surrounds . This simulates the original manufacture of the cones . Having repaired much worse, the proof is tapping the cone all round and checking the pitch with an app . As far a strength is concerned there is no doubt that the single ply toilet tissue and re paper macheing the original paper and integrating it works good and my preferred method . When repairing the rubberised surround use the but end of artist's paint brushes the match the suspension valleys . The hardest areas areas are behind the basket frame .
Can you send me a link to your RUclips channel if you have one? I'd love to subscribe if you do, thanks!
I have wanted a bluesbreaker since I started playing. I am always chasing that tone. Everyone worries about the guitar, I will put my money on the amp every time!
Yep. It's the amp. Why do you think a "guitologist" focuses so much on amps? ;)
@@TheGuitologist but what about the pickups in the guitar. I didn't catch what pickups it has.
@@TheGuitologistall the best players I know say the same..they would take a good amp over a good guitar ANYDAY..If you have been playing long enough,you can't deny it.
Wonderful to see you work on this historic amp😊
This is bringing tears to my eyes. I've had the fortune of playing my handwired reissue 2245T through a 4x12 with pre-rola's. If that sounds anywhere near what you have there. Everything else will become obsolete. What you guys are experiencing on this vid... cherish it
Talk about a unicorn! This is a holy grail type of amp for me. This should be good!
Nice guitars and chording by Dan !! I have #7032 ~ very similar down to the missing handles , broken rubber piece on the cloth power tube retainer and repaired speaker ! My speakers are the original Silverdale Rd gold label Celestions. On my amp the tremelo only works on the #2 channel. I use mine @ 110v through a controlled voltage variable auto transformer. Lucky to have the voltage selector 110v on top of the power transformer. Congratulations Dan on moving forward with the restoration !! Since your grill tear is in front of the speaker the grill can be sewn with a curved needle and thread without having to remove the baffle. I had it done on some white grill pa cabs with some grey and white thread to match the color with very good results.
Wow, absolutely awesome video! And great job on repairing that speaker! That amp sounds GLORIOUS! As soon as you guys started playing, I'm thinking "jump the channels"! Of course you eventually did, and it was HEAVENLY! : ) Clean and dirty, it sounds amazing. Awesome work as usual Brad.
now that is a beast of an amp ! great video Brad!
Another Great video I myself am so thankful you do these videos Guitologist those vintage amps are definitely where it’s at and I love your attention to detail the way you take so much pride in your work.
The best amp you have reviewed yet
That's a killer tone. Jeez. Always so amazing learning a tiny bit more each video.
Man. I had no idea this was possible. Another reason to love this channel.
Love the guitar amp repair vids. keep em coming!
Great video. Lots of good tips on here. Really loving the channel.
That is one of the smoothest buttercream sounding apps I've ever heard even clean you can hear the sustain that it has just an amazing amplifier. You cannot get that tone out of modern-day have no way.
That was great, Brad... brilliant speaker cone fix and prolly a boost to your channel.
Congrats and cheers
Barney Kessel subs for Beano; news at 6...
Just cracking: your bud is a great player. I hope we get to see more of this beautiful amp in the near future...
LoL yeah the perfect rock machine and he goes jazzy on us
Great video as always Brad.You seem very upbeat lately in your videos...Awesome!
When you said that you don't see a lot of these down your way, it got me thinking about the vintage Gibson (and other US) amps that we don't see that much of over here (UK) that you have repaired and demo'd. It's been interesting to see them, but seeing this Brit amp was pretty cool. Would be brilliant to see some more if you can get hold of any
I don’t know about Central Kentucky, but in eastern KY there were never any Marshall dealers until very recently. But Fender amps of all sorts are common, other than being old, deluxes and twins are so common I can’t see why they would be expensive
such a gem of an amp brad, and again, another fine repair
,i hope that chap gets the tremolo working too, it needs it.
I agree. And some better caps. I'd like to at least test those Hunts for leakage too.
A certain Johan from Sweden would really enjoy this amp ;)
Brilliant video, thank you so much. It was great to find Dave Simpson holds you in high regard as we all do loads of respect and support
Bless you and your loved ones ❤ Rodge David kidderminster uk 🇬🇧❤
That's because Dave Simpson is a smart man. ;)
Hey Brad!
Thanks for making me aware of the hot glue speaker fix.
Might be repairing my home stereo speaks this weekend ✊🎃👍
It's nice to have you back doing what brought us all here to begin with... You seem to be happier.
I am not going to pretend to forget the nasty things you’ve said about me over the past several months, Kevin.
@@TheGuitologist When I don't like what I'm seeing I'm gonna let you know and from what I've observed you are very much the same... I thought a kind hand might be in order - Do with it what you feel serves you best.
It's not very often that we can hear good tone on the Internet but this I believe is the exception, sounds great.
Loved your intro music HAHA!! That was awesome. I saw the font on the marshall logo in the description pic and had to check this out :-) SAWEET :-)
That neck on that guitar looks nice, i love thicker necks. I have longer fingers, ive tried out some really nice guitars that id love to have bought in the past but the necks were too thin. Id never seen that guitar there, unique I like it.
That BluesBreaker sounds awesome 🎸☕
If anyone on here ever needs to learn about the correct way or just wants to learn about anything electronic this man is the one you go toooo!!!Just to let you know.I can tell you i have seen alot of folk talk %$#@ but this dude knows,,,thanks Brad...
You're too kind. Thanks.
Very cool!!! I’m completely clueless about the tech side of amps, but I love this channel, always something interesting 👍!
My 2nd live show in a row, how lucky can one man be. Keep up the great work that you do, I even enjoy when you fix other stuff too.
Glad you made it.
I’ve always used onion paper and white glue and it’ll patch a speaker really great. I have a pair of those with the “Marshall” labels. They’re from early 1966.
The great Toneman himself! Nice to see you around here! Still have the ‘89 Bluesbreaker Reissue you reworked for me 20 years ago! Same with the Korg Vox AC-30 you did for me 5 years ago!
I always use 2-ply toilet paper where you peel it back to have thinner pieces of one ply. I thin out some white glue then dip a small paint brush into the glue and paint the toilet paper onto the cone. Works like a charm! Just add a touch of spray paint to make it match up the color of the cone.
@Ringo Starr if you have a favorable tear that works great. since wood glue will really grab pulp paper... but If you've got a situation where you actually have to put a little bit of tension on the repair and experiment with the as you're doing it the hot glue is probably the best way to go
Those two champs at the start would be a fun little stereo rig
I have a '57 Custom Champ and it pairs really well with damn near any amp for stereo. Especially like it with my Vox AC 10 w/Greenback or my SF Champ or Princeton w/12" 70th Anniversary Celestion.
oh yeah and really great with my Marshall Origin 5
Like how the Marshall amp and repaired speaker sounds-CLEAN!!!!!Sounds GREAT with both of the guitars tried.
At 27:55 in this video, let it be known, Brad finally pronounces "Tremolo" the correct way. Go'bless. I have been waiting for him to talk about the Tremolux to hear how he pronounces that one! Love yer channel long time, Brad! Cheers bud.
Beautiful chords played through vintage Marshall greatness!
I always enjoy your videos and your guitar playing. It was nice to hear your friend play and the differences between two guitar players and their styles. Ive always loved tube equipments and have messed around with them since I was a child. Thats how I learned. I just wish I would have learned to play guitar. I have tried many times just never got good at it.
Watching this from Ireland
Man, that thing bridged sounds amazing!! You friend there definitely has some cool toys!
Nice! I have always used 5 minute epoxy because it never fully hardens. I learned a better way today!
Now that is some tone, especially the clean -- something most vintage bluesbreaker demoers don't let you get to hear.
Man, that amp really screams.... beautiful tone!! 🙌🏻🎸🎶
Ok, Brad so maybe some people made similar comments to mine re; your request for (pardon the pun) “Feedback” a few weeks back. This video is awesome not only to see ( informative techie glue repair made interesting through banter & conversation who’d a thunk it)?!?but to hear those noodles & diddies through a real cool amp like that! Sweet viddy bro keep this up it’s gonna get shared! I ‘m gonna fb it right now! A really cool way to spend an hour! Dude! Rock ON!
A Bluesbreaker AND a FUTURA!?!?! My dream rig.
So glad you used the camera mic.
Wow that amp sounds great!
Anybody who's ever used a hot glue gun knows what a PITA it is to control the flow. Once you push on the trigger it starts, but it continues after you let off the trigger. Then you have to deal with the "strings" that hang when you pull the tip away. This is a job well done.
Edit: Forgot to mention those 2 guitars. DAMMIT MAN!!! Absolutely beautiful.
Wow! The sound of the old Marshall is superior to the new stuff. It's got that beautiful thump and grind.
I have always used the toilet paper, and rubbber cement with good results. I like your style. Good job Brad.
That amp is the Creme ! So smooth !
I like his play style! nice video
Sounds phenomenal
That's pretty much the best Marshall I've ever heard. Glued speaker and all.
Holy S! That one is rare and worth a fortune. I can only make do with my 1989 RI that was tweaked to vintage specs by Don The Toneman Butler in California.
I bet it's still pretty decent, right?
@@TheGuitologist Yes it is, sir!
Thanks for reminding me Brad! Gotta make a beer run. Be right back!
Get me a sixer of some pale ale.
@@TheGuitologist On a budget, have to get the Champeein of beers. But it's better than an IPA... To me they taste like fish cum and flowers... Ugh.
Thank god I read your description first Brad ! Was ready to rip ya a new one about a 64 Bluesbreaker ! No such thing in 64. BUT alls well.
my question is did Marshall out source other speaker manufactures and what companies did they use ? Were "Pre Rolas" just relabeled ? im not sure
Incredible amp. Thanks Brad
That flying V 😍😍
Very cool amp
Brad, good deal on you getting to demo the AMP, and those axes. However, I am really surprised you didn't have a go at Hidaway. Just to hear that on that rig would have been awesome 👌😎Cheers
That looks like a seriously fun afternoon.
Just fun as Hell watching you guys appreciate those things. Y’all even said and did things way outside of my expectations. Great video…
🤔 why not try some of the old iron-on “Stitch Witch” hemming material to patch up the torn grill cloth? Wouldn’t that work and theoretically be audio transparent? Okay maybe on a lesser amp to experiment but just a thought.
The stuff I showed is probably very similar.
those guitars sound phenomenal through that amp.
I'd have to imagine that gluing the cone is going to have a noticable effect on the sound. I work on amps myself, though never had to repair speakers like this.
Killer Marshall👍👍dude sounds good 👍👍
Thoroughly enjoyable. The dulcet tones of well made instruments. Still want that lunch box amp! Cool flower cabs, too. Never got to play an actual old Marshall so I converted an Ao35 into an 18watt lite with a new OT. I was pleasantly surprised with the clean tones! Im stoked about the overdrive ,of course.But with a good speaker, the cleans can be just as inspiring as the blackfaces I’ve tried. It’s a great amp.
Woo Hoo like number 200! Great job on that speaker.
Not a big fan of Marshall amps...but after hearing this i really love this amps sound. So warm and open...that cranked crunch sound is not fuzzy at all.! Just crunch perfect..very very nice if mic'd up..💖👌👍🤘🤘🤘🤘
Good stuff dudes. Nice video.
I would have never thought hot glue would be good for speaker rips and tears. The glue dries as inflexible
as the stick is to start with Brad . Although it is a strong repair by itself. What an amazing amp!
Sounds like "buttar"! Uncle Doug eat your heart out at this one!
Put a thin layer on a sheet of paper. It flexes very well and does not tear or crack.
That carpet is most likely the old Hoover vacuum bag material. I heard that what they used because it was right down the street from them.
that bluesbreaker and korina futura are rad as FUCK!
Awesome. I have a guitar speaker with a damaged surround. Will this work for that, and would it work on a foam surround?
That’s some killer gear right there, Brad. Schwinnng
Your amazing so educational Sir
Brad have you ever tried brushing on rubber cement clue on a cone
Those kt66s are beautiful
Man, that Futura/BB clean tone is to die for.
Hey, great video! I have been trying to find a JTM 45 mark IV Super Tremolo, like my one. It was made in 1965 and has the original KT66 & GZ34 valves and 2 x G12 Celestion speakers. It sounds amazing, very clean sound and can be loud! Also runs very quiet which is great. I have been searching and can’t hardly find any pics of it..
Gotta check this out for sure 👍🤘a blast from the past
When Brad was playing the Flying V towards the end of the video it was like a Foghat sound. I wanted to hear Slow Ride!! Nice friggin amp!!!
Nice piece of gear Brad.
Wow. It really sounds good. From a modern day guy, I can see why they would want this stuff. People might say they don't have a lot of distortion. Maybe not excessive, but this goes a long way and all of it is good sounding. Perhaps the guitar plays a part as well, but boy, it's lovely. And this wasn't even miked. He's a great player too, really nice groove.
The thing with these kind of amps is that you don't have to need the sound that's coming out of it for your music. You can just get inspired by it and forget what's your preferred tone.
Excellent vid.
Great amp enjoyed the video
great video love the tone of that Marshall
That thing is a beast!!!
Just awesome.
Cool, thanks, the sub was with that one. I'm not only a guitarist I'm a sound engineer and I have my own little club and street fair sound and light rig. Thankfully I have never blown a speaker but if I do I will try this. Had a bass port fall of of a QSC sub. Gorilla glue fixed that stringer than it ever was.
can you spary flex seal on speaker paper ? would it alter the performance and sound or damage it ?
Cheers for sharing that Brad, I was hoping to see you sort out the trem function too - will that be another video.. pleasseeeee?? All the best Paul in the UK.
Maybe he'll bring it back one day for a full service. We'll see.
@@TheGuitologist I hope so Brad, you were grinning away like a kid in a candy store with those tones - it was really great to see you have some genuine joy and fun in your life after the last couple of years. It reminded me of going back to the late 70s, when I was 13 and had my first electric guitar for Christmas ( I still have it) and heading to Rock Bottom guitar store in Croydon and looking for an amp.. they had loads of old Marshalls, Hi Watt, HH, Vox etc etc and guys in there trying them out. That buzz. I saw it in you again on that cone repair and try out. Keep on, keeping on.
What a groovy amp! 😎
The Iskra, Phillips caps will have date codes on them! That amp was built in the back of the Marshall Silverdale Rd. shop in East Hanwell.
are the speakers accurate for this year i mean Marshall was deep in "Pre Rolas and Celestions" Did they have to out source ? the magnet style on this one I have not seen in any i have seen. just curious
@@ianhaynes333 so it's an alnico celestion ¹² inch speaker, very old !
@@ianhaynes333 they first came out in the 50s made into the early 60s...Celestion B024 speaker 12w
A true geek out session. Cool.
That tear on the cloth looks so clean cut I can't help thinking it's probably a studio thing. You get the mic a lot closer to the cone if you make a small hole on the cloth.
Edit: and later in the video it's mentioned the amp is from a studio!
And the hole is the size of an SM57 head.
When the Futura/ Explorer and Flying V came out, I was like remembering. They had these hanging up at the music store in the 70s and we weren't allowed to try them out because of the price tag. All gold hardware...they were pretty to look at. I was able to try out an original 57 gold top Les Paul once though... that was sweet.
That this is HUGE and glorious!
Fair play, tidy job! 😎🎙🎸✅
I wish i had this kind of talent. I wish i had that kind of amp too....damn thats sweet....both of em
Love this channel. If you had to only have one amp to play blues; what amp would it be?
Great video Brad. You have yerself a unicorn right there. Jeez does anyone else feel uneasy with the way his pal holds that V or is that just me
