i have a very vague understanding of pedal power supplies, i believe there are two kinds: PSA and PSU? im not sure. would some of the power supplies work on some pedals and not on others? could someone please explain this to me? thanks
As long as you match polarity, voltage and AC or DC and don't exceed the given amount of amperes any supply works with any pedal.
If the pedals require 9 vdc, as do most Boss pedals, just buy a 1Spot power supply. It's made by Virtual Sound. I use one to power about a dozen pedals.
