I just bought a used Orange Two Stroke pedal advertised as "mint" condition and it appears to have a problem. I think it sounds pretty good when the EQ is engaged but when you click the pedal off, bypass mode sounds awful when you pluck the heavy strings pretty hard. The note sounds really farty like there's a short in the cable or like the power source has been overwhelmed or something and it can't produce the note. I'm wondering if the pedal might be a lemon or if other people have encountered this with the orange two-stroke?

Note that I've tried the pedal with a fresh battery only, with a 9v power supply, and with a 12v power supply and the pedal sounds pretty much the same regardless.

PLEASE ADVISE -- If I'm going to send this pedal back, it needs to be soon.
