Hello everybody.
Do you know this Mathis Audio Tech OD Texas Tone? It sounds very interesting if you like sound Steve Ray Vaughan style, or Jimi Hendrix.

Official page where you can find some video: https://www.mathisaudiotech.com/en/product-page/od-texas-tone

I'm very curious about some detail in the schematic.
Two transistors: input and output buffer?
Four diodes: what kind? Connected like... Timmy? Jan Ray? Bluesbreaker?
Then treble and bass control. There's more than a way to make the tone stack, of course.
And more than else the TT control. What's that? A flatter and smoother Big Muff tone control? Or more transparent Tilt Tone control?
 
It is yet another Timmy clone...

I uploaded a layout for it on my blog. Somebody didn't like to have this pedal traced and made Blogger take it down.
I usually stay away from pedal drama and hopefully this thread won't burst out...

The schematic contains one error though, the voltage divider for Vref is misprinted but it is an easy fix.

I’d assume the 2 transistors (j1&j2) are simply input/output buffers, and omitted from the schematics?

Looks like they might be decoys.

There appears to be the same number of resistors on the PCB as the schematic (aside from the one obscured by the breakout board, which I assume is the LED CLR), so not enough to support buffers.

Is that common to see decoy parts used? I’ve never seen it, but I haven’t traced THAT many pedals either.

Yep, the transistors are decoys and they happen to be MOSFETs...😏

Sneaky. I was thinking they could possibly be clippers, especially based on their back to back orientation.

I suppose that was the intended result. 🥸


The marketing blurb is ... well ... something.

A couple of the high notes:
  • Developed from frequency response analysis and numerous dynamic tests on this vibroverb 64 amp with the famous vintage JBL E130 HP.
  • TT: Texas Tone is an innovative setting that has a general action on the whole spectrum and slightly alters the settings of the pedal.

Hmmm I’ve seen similar claims by another pedal maker— especially how he calls his second tone controls in his pedal that is essentially a Zen Drive copy, a “JBL speaker emulation”

Glassy Fart? LOL
 
As I understood it, quite the opposite. He was very well applauding the efforts regarding the frequency response analysis and numerous dynamic tests that were involved in the development of this innovative pedal — lauding the efforts made by Paul Cochrane.
 
So, that schematic is the OD Texas Tone? A Timmy Clone? And the TT control is just that PT 5k pot?
I built a Timmy replica, but it doesn't sound so sparkle, nor so low gain. It has more grit than this pedal.
Or maybe the Stratocaster used in the demo are very low output pickup. My guitar are a bit hotter.

To be honest, 90% of the great tone you hear on pedal demos are the awesome amp they're using. A Timmy is great, but it's only putting some nice icing on top of a great cake. Try a Timmy through a shit amp and it'll still sound shit.

That marketing blurb is something else. It almost makes me want to get into the pain which is pedal building.. the Sheepylove Honesty line.. this is a Timmy with a slightly different EQ, because you want a Timmy but you want a different name on the label.
