Title: What happens if...
Post by: MrBump on May 05, 2010, 11:51:28 AM

... you plug a 9v pedal into a 12v adapter?

Does it go boom, or blow out a bit of the circuit?  Or can most tolerate the extra power?


Mark.

I'd say it depends on the pedal, some have protection circuitry, some don't.  Some pedals can run from 9V to 18V happily and are designed to accept greater voltages.

I think most would be okay but some would die :(

I'm hardly an expert but I think it'll mostly depend on the value of the electrolytic caps used. Most small ones are rated up to 16v so you *should* be fine with 12v, but be wary of 18v power supplies unless you know what's inside the box.
Often using a higher voltage supply can give more headroom, but if in doubt use 9v.

The advice given above is correct for most pedals as the components should be able to tolerate the higher voltage.

I would be wary of using a higher voltage adaptor in a digital pedal (although there wouldn't be much point).
