Okay, so I just finished circuit bending two pedals -- a third generation DOD FX25 envelope filter and a DOD FX70 Metal X.
Setup goes: busted Michael Kelly Club Custom 5-string >> pedal >> 10 Watt practice amp (set flat). The amp is mic'd.
Clips go straight bass, then with effect, then with the circuit bend engaged, then a little messing around with controls.
FX25 FX70
Anyway, enjoy, sorry for the cruddy playing, and I'd love some feedback.
