The PedalPCB Proposition Distortion is based on the legendary and extremely rare Rockman Ultimatum Distortion Generator pedal.
Special component considerations
This project requires a selected JFET for the compression circuit to function properly.
Alternatively the compression JFET can be omitted and jumpered. This will bypass the compression function and increase dynamic range.

Ordered and built up 2 of these right when they came out- i had high hopes and low expectations, but this circuit smashed the latter. Totally nails “that sound” right out of the box. Ton of harmonics, honky mids, very usable eq, and does plenty of great tones besides the classic Rockman crunch. Testing ended up playing DL Hysteria and Boston riffs for an hour. So much fun and a really well done circuit, nice job guys!

Another fine project release from PedalPCB. This circuit nails the Rockman Ultimatum Distortion Generator – without the buffered bypass and ‘Low Battery’ indicator. Fits nicely into a 1590BB enclosure. Built three already and ordering another 20 for a collection of clients. Great job Robert!

This the first pedal I’ve built using somebody else’s board (I normally develop my own circuits and PCBs) . It certainly did not disappoint! Very nicely laid out board, and it sounds exactly right. I had to try it, as the Ultimatum is the one Rockman product I’ve never had. Highly recommended. (if there’s anything I could change, I’d enlarge the pads. I find them on the small side for hand soldering).
