FWIW I power my B3 with a OneSpot and don't have any noise issues.
Thanks NYC, the batteries will solve the noise issues, we only play a couple few times a month and im trying to cut down on wires everywhere, and using the mxr brick with the B3 is outta the question (should have spent the extra $ and went with the voodoo labs, its got isolated circuits) and besides batteries, a separate wall wart is what keeps the B3 noisless for me. So it's batteries until I can afford the voodoo labs, thanks y'all :thumbup:
