Hi friends!!!
I have got this pedal and I'd like to mod it... I'd like to get from it more distortion and less fuzzy sound.
Also, it would be cool change the general tone a little...

But there aren't schematic on the web, I have done some pic of pcb front and back... :horsey:

anyway its a 401 line driver plus a Black Cat OD/freddy fuzz in series,schematics are around,its just a matter of adding a couple of diodes/leds and tweak the tone control.

:applause:
thanks for your replies man.
please, could you send me the schematic? giudis78@hotmail.it

I've seen the 401 and black cat schematics but I don't understand...where are all those J177?
And diodes are in the booster side, aren't they?
