I have the pleasure to present my Too Many Knobs prototype.
The circuit original was designed by TimEscobedo, you can find here.
I constructed this pedal too fast, so i don't remember the assignation of pot (just the right top for the volume and the middle top for the crossover distortion).
This distortion have got many possiblity of sound and I will make other demo video (with guitar).
If you are intestered in this pedal, i can make one for you for a approximative price of 60/80 euros.
To be continued...
