I'm curious about this. Dad apparently bought it a few years ago (it's a bass pedal), and I really have no idea what it's supposed to do. I tried it through various amps (all solid state), and there was always this sort of hissing sound I couldn't get rid of. The distortion setting nearly killed my amp, or the sound it made sure made me think that.

So, anyone have any idea, you know, what this device was intended for?
