Fulltone Fat Boost V3, searching the scheamtic

[JackSkellington]

Hello!
I would like to build, one day, this versatile boost: Fulltone Fat Boost V1. There's at least a pair of veroboard layout around.
But there's the V3 version with not a simple Tone control, but a Bass and Treble controls.
There's any chance to find a veroboard layout or at least the schematic.

I read that the Fulltone Fat Boost is a copy of the Amz minibooster, maybe there's some mod in this with a treble and bass controls.
I'm keeping to search, but some help is well accepted.

Thanks!
