Here's another Lotus pedal and this one excites me a lot more than the Snowjob.

Here's a drawing of the PCB:

Note a few changes:
Both 2.2K are actually 22K
The upper 100K is a 1M.

The pads with X over it are grounded.
Upper transistor is 2N3904 and bottom is 2N3906

Except for the 100K instead of 1M
