Here you go as requested, this is the Tech 21 XXL distortion layout minus the CMOS switching and the input buffer of the original circuit. You may want to add a capacitor from
0.1uF-1uF in the jumper labeled as "
Cin?" and also changing the biasing ressistor labeled "
100K??" into a
1M resistor. Anyway, that is just only a suggestion. Pots are all 100K LINEAR.
