It doesn't come with a DC jack on it, just battery, which is why i thought wiring it up for a centre -ve adapter would be ok. i understand that most pedals ground through the sleeve which is usually the +ive.
I'm asking cos after i connected it up to work off my adapter i sent it to the repair shop to have the pots looked at (they were crackling), paid £15 and took it home. Didn't work. Took it back and collected it Saturday and was told it was £30 as i'd blown the transistors (the repair guy had taken it upon himself to rewire it "correctly"), so when i connected it up it blew
Just want to know if i'm in the wrong really, i took advice from other forums and just switched the wires around. If i'm wrong i'll pay up, if not i'm taking the pedal and getting my initial £15 back as AFAIK he didn't fix the pots!
