Wasn't sure if this had been posted before. (Did a search and didn't see it) I was actually watching some vintage Fender amp vids when I ran across this. Love how the post was titled "Fender Tremolux Killer!" (y) Hans and his book are featured as well.:cool:



That sucker sounds amazing when both channels are paired!!!

Not worth going past the unpacking with deep woods internet, sad he couldn't wrap it up in ten minutes, I wante to hear it.

The problem for me with fantastic old amps is they sound absolutely like dirt turned down too much for bedroom level playing, terrible, and even the smallest ones - I just bought an 8W 1x6" 50's tweed amp - are really incredibly loud in terms of decibels, and the clarity is too much.

This is why SS sounds so good a stupid low volume levels, you're not having to deal with the amp not being open enough to sing.

So ultimately these tube amps sound best opened up, made to be loud to compete with other instruments.

Also to note, humbuckers can sound raspy as all get out through these, but single coil pickups have a lot more headroom if that makes any sense, the cleaner the pickups, the louder a clear tone you can get. If you wanted breakup and you're playing lipstick pickups, pedals hardly even help.

But this mod I really like. It only makes the amp more versatile and user friendly. Old amps w/ 2-3 instrument inputs, a mic input...all a waste of space IMO. Without watching this bloated feature film length video, just go to about 1:00-1:01mark to see what he did and how it sounds. He used the old mic input jack as the lone instrument input, then used the next two input jacks in line for an effects loop send and return, then lastly, he pulled the final input jack and installed a two way toggle switch for single channel or a combined "beast mode". Sounds killer! I'm not opposed to mods on vintage. A player should have what works and sounds best for them. When you find your happy place, it matters a whole lot more to me than having a factory spec amp that can't get you what you really want out of it. Being tools that spark creativity should be the sole purpose of even having musical gear. I get it if you have your player grade rig, and you collect original vintage on the side for the sake of collecting. My 1940 Webster/National has all the original caps, tubes, everything, and I'm hesitant to have anything done to it besides maybe a grounded 3 prong plug added, but I rarely use it. My 56' Champ, I have no problem letting my amp tech go to town on. I need it to work the way I want it to work. There are countless museum quality examples out there, and mine was far from it when I got it. This Guild wasn't museum quality from the start either. And now it's an amazing little amp (better than original IMO) that should get regular use...as was originally intended.

Eh, "vintage" is just... time. Doesn't neccesarilly mean it's all that special. Especially if it's in player condition from the start. Not like the 200+ yr old old growth wood of a vintage acoustic. My first amp I ever bought new, a Peavey Renown back in 84 is also now officially "vintage"! (Yikes) Damn thing should have come w/ a hand truck, back brace, and a years' supply of ear plugs (more for the crap tone than volume!) That amp should be gutted! (Or at least be put on a Jenny Craig diet!) :LOL:

When you really think about it, The Beatles never played vintage gear. It all is now, but it was all the latest brand new out of the box gear at the time. Fact is, there was great gear, average gear, and crap gear then, just like there is now. If you can make average gear great, no matter what era, (as long as it's not some ultra rare museum piece) I'm all for it.

Darn I missed that, the beauty of terrible internet.

The last tech I took an amp to, somewhat of a jerk fresh in from TX who fking left his house to go fishing when I was on my way into town to pick the amp up "because I took too long", like wtf, never had anybody do anything like that before... but he turned around, went back home, to his fancy house with two bitcoin computers in the entry way - I'd never evern heard of bitcoin computers - well long story short as you can tell... he flippin modded my '66 Blackface Bassman to the point where it broke up worse than my Marshall JMP50W and I had expressly told him "don't do anything like that to it, I already have a Marshall".

Something to do with a post phase inverter, and negative feedback loop yada yada, and I had to take it back and have him undo his stuff, he was not happy, and the amp still never sounded right after that and I sold it.

The channels were bridged inside somehow, if you plugged into channel 2, normal thing to do, the channel 1 volume could be used to modulate distortion. I called him and said "what is that?" He said "I have no idea".

The bottom line is DO NOT let any tech mod anything beyond a grounded plug, and that's it.

It's not as reversible as you think.

On the other hand, Gar Gillies, Garnet amp guru, Canada's Leo Fender of amps but through the rocking 60's/70's scene, advocated "improving" any of his amps he ever built, if it needs it, to keep up with the times, originality means nothing, improve on the platform if it needs it and you know how, but most important, keep it running right, originality of parts means nothing.

That said I replaced the Marsland speaker in my Garnet 1x12 Reverb combo with a Weber, for the better. Amazing little amp, basically a 5E3 Champ with on board Reverb that's actually as good as Fender, and Tremolo, in a 1x12" combo that's small, light, and crazy loud with unbelievable clean headroom.

Well, if this guy ever moves to my area and runs for public office, I'll keep a note of his snide comments. Otherwise, he's fully gained my trust that he has a vast understanding of old tube circuits and how to get the best out of them. (If I start judging humans on what comes out of their mouths, I won't ever be able to watch sports, watch a movie, read a book, visit an art gallery, or listen to music anymore. a decent % of ALL humans ever are A-holes that say A-hole things. That shouldn't make you cancel a sizable% of the world's cherished art. Try filtering a single line of negativity without outright rejection. I'd likely have to toss have my 1/4 of my record collection if I went full on cancel culture on it. :cautious::unsure: That ain't happening. There are lots of A-holes who's art I admire. ;)


Fact is...ALL old amps require new caps at some point. Most really old amps require soldering just to bias new power tubes. Nothing can ever stay 100% original if the amp actually gets... used. As it absolutely should. And I am all for using what I have during my short time on this rock hurling through space. If I can get more satisfaction out of it during that time with a modification...I will. It won't matter to me a single bit when I'm a sandwich bag full of ashes. Best to enjoy the ride. Sorry, but this guy absolutely made this Guild amp 20X better. You'd never have it close to being in the same sentence as a Tremolux otherwise. In 20 years, young kids won't be playing these anymore anyway. Line 6 will be "vintage" by then.😔

<shrug> I've caught him in questionable stuff before, and he hasn't been able to find solutions for some things that were obvious to me. I don't particularly care if the amp sounds like everybody's favorite flavor of vanilla. If I ever run into it in person, I can always repair the damage. <second shrug>

That’s extremely unprofessional of the man. When I still fixed and modded pedals for the general public if they said just fix it don’t mod it I didn’t monkey around with anything that didn’t pertain to making the unit function again. I had something similar happen last year when I asked around to have my Traynor YSR-1 recapped. I guess I could attempt it myself but I’m just now messing with tube circuits so I don’t want my Traynor to be a casualty as a result. I asked a tech a few towns over and for whatever reason he kept on suggesting that I let him mod it to be a Marshall Plexi which is a common mod for many Traynor amps but I knew my YSR-1 wasn’t the usual design and I came to love it for being it’s own thing and I love having reverb and trem on the amp. Well despite my protest of having the amp modded he just kept pushing to get me to agree to have the reverb and trem circuits removed so their triode stages could be used to make the amp have more gain on tap and do this and that to make it a Marshall until finally I just hung up. I get it, the plexi is a fine amp but I was raised and had the motto of the customer is always right. I suggest mods when people ask me to make treble boosters, fuzz circuits or when repairing pedals but if they tell me just once to leave it bone stock I’m not gonna push the issue just out of respect for the client and their own pursuit of tone.

OMG, keep these freaks away from vintage Traynor goodness.

I should learn to recap myself.

I'm reading Dave Hunter's book on amps, hard to find, super long out of print, 2005, he says things like "you can easily find amps like Tweed Champs for $500", lol, not anymore.

Anyway, Hunter is really full of it, but in a good way, and reading his stuff I have learned a whole bunch, like the size coupling caps make all the difference in tone", etc, etc.

In one chapter he advises finding old tube PA heads, and changing the EQ of the amps towards guitar by changing values of coupling caps, all of the research has already been done.

I've only skated through the book, The Guitar Amp Handbook.

Also bought his other hard to find Tone Manual book, again a lot of words but they're all about guitars amps and pedals, so how bad can it be? ;]

I bought both these books during the pandemic. Learning stuff is exciting.

I also have little faith in internet lore. There is some really good information out there, if you can find it, if you want to be glued to a computer reading forum threads.

I have Gar's book, because I bought one of his amp last summer, but there not much text, mostly notes, observations, and circuits.

Gar was responsible for the Guess Who's monstrous guitar sounds, at some point building the Herzog, a 5E3 circuit in a box just to overdrive other amps.

No to brag, but I'm in effin tone heaven right now, I have a '57 Silvertone 1331 Champ circuit 1 x 6" on an old school chair, turned around so I can see the tubes glow, and the Garnet 1 x 12" that now has a Weber Signature Ceramic not Alnico, turned aroud also, sounds better, it's got some chunka chunka bass, both being fed by a 76's Fender Tube Reverb - the mild one - with 4 tubes instead of three, and a 6V6 instead of the 50's tube , fed by by 12AX7 powered Varidrive, and two old CMATMOD pedals I've had forever, a very early Boost, and a script logo Gray Ross clone compressor, and the tone is incredible.

Not to underestimate the Silvertone 1x6" amp, on the channel B of my old Horizon Selectaline glow in the dark A/B/Y box, it sounds amazing by itself, better bedroom amp than the other with 12" speaker. Both together maybe the best "amp" I've ever played.

The Garnet has both Reverb and Tremolo, all the way off.

An oddity about the Garnet circuit is that the tone circuit is completely backwards, all the way open and it's bassy and bearable, go toward close and it's bright city, it's almost like a contour, clever, but I think Gar was known for his unique take on the tone stack.

The Reverb is killer, easily too much. Also weirdly interactive. To understand this amp would be very educational. When you dime the Volume, it's not that loud but you can max out the Reverb, sounds great, but turn the volume down, you have to turn the Reverb way down or it's overpowering. Tone stack works the same way, very interactive. When you have the Volume dimed, you can dime both Tone and Reverb and the whole thing sounds fantastic, rip your head off loud and this is a three tube 12AX7 single 6V6 circuit, probably SS rectified.

My biggest b*tch about this amp is it's just too loud, and turning it too much down just kills the tone.

The Trem works great, click pot on/off, but too fast for my taste when backed off all the way. I'd like to slow it down. I like really slow Trem.

I had a Reverberto, dang it who made that? I got CRS. Gorgeous tweed low serial number unit, prob worth a small fortune today. The trem was too fast and me not having much more than my Fluke 23 a soldering gun and a some guitar Orange Drops before I slowed the Trem right down. Left the original cap in place, just unsoldered a leg, for easy reversal, but why?

I often feel that most Phase Shifters don't cycle slow enough either.

This is weird, but playing through excellent tubes amps pushed me to find the exact pedals I was using 20 years ago, so what do I do with the 50 others I've bought since, that are all at best redundant, at worse useless = list on the Verb & $$$.

Here's the jam zone, it hardly looks like someone with a gear hording problem at all ;]

Is your Traynor YBA-2A 6V6 or EL84? Such a rare amp!

I see you have a Tube Driver pedal with the added bias switch. Last year I sold mine which was the same version Eric Johnson uses. I had that thing since high school and loved it to death, but it took up so much room on my pedalboard. I may get a newer one like yours with the bias switch. Such smooth creamy tone from that thing and the perfect preamp gain stage/overdrive.

It's 6V6, so of course I wanted it to be EL84, but in time finally realized that 6V6's were my favorite output tube, so I was ahead of my own curve.

I almost bought the matching EL84 Bass Mate combo last summer, I thought I could have both, but ended up buying a 1974 Garnet 1x12" Reverb/Trem combo instead, from seller in Ottawa.

So now Traynor and Garnet are my favorite tube amps.
