Tech 21 XXL


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.

DNA Gain F***er 2


This is the layout of the Gain F***er 2 distortion from DNA Analogic. Pads are provided to FETs and bipolar transistors that has different pinouts. Pots are all 100K. I would recommend using log tapers at DRIVE and LEVEL controls, a reverse audio taper at CUT, and a linear one at the FXXX control. Enjoy!
