Used, tested with a battery - if it matters, Little Mark 3 and 1X12 Aguilar cab. According to previous owner, pedal worked fine and yes, he's reliable guy. when I tested, sound was way too uneven, not much of sustain, either. no matter how I tweak it or follow the samples on youtube/web, it just sounds different and not usable. I don't really have much experiences with synth pedal, I'm thinking I'm doing something wrong. any thought or advice? I tend to roll off master tone a lot and my bass has pretty low action btw.
