Stupid voltage questions.

    I just picked up a Digitech Talker pedal for $10. It worked when I bought it, but when I got it home it doesn't seem to like my Voodoo Lab Pedal power. It turns on, but doesn't function correctly; lights come on, and some flicker. It requires 9.75 watts, 820 millamps. Is voltage flexable? I seem to remember hearing that a 9v powersupply is not exactly putting out 9v all the time; it varies. So I guess my question is this: do I actually need the exact 9.75, or is my pedal just broke?

    Are you sure the polarity matches?

    I've tried both polarities. Same effect.

    Eek. Maybe the wrong polarity cooked something. Sorry to say it.

    That's possible. Nothing on the pedal or in the manual indicates that what polarity it is. It just says "Use Digitech power supply only". Bastards.

    I think there's something illegal about that. At least in the US. Or, the pedal is not powered by a UL approved device, meaning "don't buy it". I'll bet you lunch it says what the polarity is on the adapter. Of course, you'd have to have the adapter to know that. :)

    OK, I discovered the problem. Nothing in the manual or on the pedal states this, but this thing runs on AC current, not DC current. I went out and bought the correct adaptor, and all is well. I'm glad I didn't screw anything up by runnind DC into this thing. I'm a happy boy.
