I recently bought a Bad Monkey Effects pedal off craigslists for 25 dollars, new. It did not come with a power supply and I'm afraid I'll ruin the circuitry if i use the wrong adapter... Right now I have a 9 volt negative polarity AC adapter and was wondering if that would work?
6 string bass =]
it should tell you on the bottom of the pedal.
i used to be a mod, then i took an arrow in the knee.
Most pedals are negative polarity.

If this is on the bottom, it's negative.

yep they are center pin negative, they take standard Boss style adapters.
