This is likely to be a less comprehensive list than the vice verses one...but...I'll start. Fulltone GT-500... I've read almost nothing but melancholy to hateful on this pedal, and then a scarce few good. But I just picked one up today and it is holy flippin' good. I understand there were some major discrepancies between the original gray version and the newer red one, which I got, but with all the downs I was not expecting what I got. It hit exactly where my Barber DDC was lacking. Anyway...your turn!
