i got a 9v Hpro adapter to use for my overdrive pedal, when i plugged it in it started to make a real loud noise and didnt work when i plucked any strings. now it seems to have broken my pedal all together, i tried replacing the battery and chords but it still wont work.

what do you think i sould do? should i contact them?

your pedal is ****ed.

thats why you ALWAYS check the voltage AND Amperage of the pedal and adapter.

The voltage was probably wrong and it probably fried the electronics inside the pedal.I dont think you could fix it unless your good w/electronics and schematics and stuff.

I'd start by looking inside for burnt out parts.

On most analog pedals voltage isn't really an issue(and not in this guys case for sure; he got a 9v adapter), some pedals sound cool on different power supplies. Going too high can burn out parts, and of course amperage could do it. I wouldn't go above 1000mA. I run 9v pedals on 1000mA 12v all the time, you just need to have a basic idea of what will start burning stuff.
