havent tried the devi, but i bought a ppb about a year ago. That thing is amazing, straight out of the box with a pos cort and a behringer 30w combo it sounded great, and with my spector rebop into an eden wt-800b it sounds amazing, plenty of bottom end (plus a blend knob) plus more gain than you could possible need. also if you turn the saturation up past 3 o'clock or so you start to get some nice glitching
the only problem i've had is that the knobs have come loose a bit, but this is an easy fix.
oh and it sounds great on guitar too
