I'm quite interested in having a look at this if anyone has any info on it please.
It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?

He dropped it to $195 on TGP. Word of warning, tracing those is a bitch and a half with the trace routing and tight component placement.

Mad Profs. The CB line is a bit easier to follow though.

I found the easiest way to trace a Mad professor effect was to remove all the components, that how i got to the end of the snow White auto wah trace :D

Ya, but that's still a total PITA. I wound up having to do that for the Himmelstrutz Gramps after a degooping and didn't even feel like tracing it afterwards. Still need to get on that...

Hi!

I am interested in this pedal but I don't find any schematic, pcb or guts photos. Anyone knows anything about it? I am really interested in it. If anyone have it could post the guts. I can design the pcb from the schematic.

Got one with no bottom plate and missing knobs in a trade. Among others. Unit was deemed faulty and someone had already tried to repair it. Grrrrr. Only thing wrong with it was the "Level" pot, C50K. As it is on par with the rest of the MP HW pedals, i have little interest in reversing this. But just in case someone was wondering, here's a couple gut shots.
