Which type of PI for the john mayer tone

Post by huub8 »

I own a geloso 1040 amp that I'm converting to sound more like the sound of john mayers amp in the continuum album. The first thing that I would like to do is change the PI into a long tailed pair setup.

But after which amp should I model it, I was thinking about a fender, but which one? I myself was thinking of a fender bluesmaster junior (but that’s just based on a single youtube video).
Might marshall or other be better?

I do want to reuse the ecc81 tube and power tubes (if reasonably possible)

(I intend to redesign the preamps after this too, as well as the tone controls, so basically everything)

The original schematic:

(I know a fair bit about digital electronics, and have been looking into the workings of tubes the last couple of months and I think that I'm starting to get it, just so you guys know how technical you can be)

What amp/s are used on the album?

Mostly a signature Two Rock amp, which seems to be mixed with several fender amps (including the blues junior).

I doubt that.

There are so many secrets that are used in recording an album it defies reason.

Just refer to the foundation of rock music to see what they actually used in the studio.
It will blow your mind!

Think Jimmy Page, used supposedly a Supro vs the on stage amp.

The tone seems to be centered on the "Heart Breaker" song for the mojo tone.

Rather than zero in on a famous artist tone, why not create your own sound that is unique to? :lol:

Just kidding of course but when I did finally find the amp that defined me, I gave up trying to sound like the album tones since most of the time they didn't use any gear that they used live.

Good luck! :D

I plan on developing my own tone along the way, but as a starting guitar player, playing a lot of john mayer songs, I figured this would be a decent starting point.

Hearing this:

I figured that I could get reasonably close with just an amp (close enough to be john mayer like sounding that is)

But, considering my other tubes and layout, is the fender blues junior really the best PI example to model mine after?

Wasn't his two rock stuff based on an ODS? That would be a good place to start. A fender twin would get you close enough :P

If you're a beginner-level guitar player and you want to sound like John Mayer, the most important two things to do are (1) take guitar lessons and (2) practice. Modifying your amp to have a different phase inverter is probably about #497 on the list, if it's even on the list.

But if you're just itching to do something with this amp you have (it's a PA amp? 2xEL34, 3 little tubes?), why do piecemeal modifications or try to re-invent the wheel? If Mayer's sound is basically clean Dumble , then build a clean Dumble. Look at the several threads you'll find here on the "Small Special."

A 50 watt version of one of these should be pretty easy to build into the Geloso. Two big tubes, two little tubes, four knobs, some switches.

Guys here have built JM 2 Rock clones, but they have more tubes, knobs, switches, etc. than your amp. You could still possibly make one, depending on various factors, or you could maybe make a simplified version without reverb and just a passive loop, but if you've never build an amp before, you'd be better off with the Small Special.

Any old 6L6 w/reverb Fender will get you close enough. Then, once you've learned your stuff, you can mod that Fender into the exact JM circuit if you want. That being said, I'd be a much better guitar player today if I had never found the soldering iron. I'd rather be a great player through a Line 6 than a mediocre player through a Two Rock.

I think that I'll try modelling it after an early fender then, and try the dumble with a different amp.

What do you guys think of this fender deluxe in terms of tone?

(ps: I'm not building this amp to sound like mayer, but just to build an amp, and I needed some tone ot persue)

I'm thinking a 5F6-A. It is the foundation of a lot of modern push-pull guitar amplifiers. http://schematicheaven.net/fenderamps/b ... _schem.pdf
