- Remove Q13 and its circuit to get the octave effect out, as the picture shows, its possible to remove the 1k resistor initially to test this mod.
- Replace the 10K in Q14 base for a 1K resistor, to increase the stomp volume.
- Jump the part of the mode switch and cut one lead to add the volume control to the boost mode.
See the picture:
