Pots are mounted on the reverse side of the PCB. Straight mounting pots keep the sense of the varistor the same.
Behind the 12V->9V converter chip, there's a 3-position switch to replace the stomp switch.
It provides ON, BYPASS and BLOCK. BLOCK ends up being useful.
Jacks are 3.5mm to save space and be consistent with Eurorack modules.

The Distortion 250 seems to output less than the Distortion+ I used to have, and the gain has less fuzz until the very top of the pot where it gets very strong. Could be an incorrect component was installed.
