Anyone know why my DD3 won't work when running on a 9v power cable but does work on battery? The light comes on, but there's no effect.

Oh, yes - everything's up and running. It's an issue with the output thing, I suspect - but there's power and yet not effect. Weird.
my wah had the prblem where it wouldn't work when i turned it on. i think i bent or hit something where the power supply plugs in. i just used a zip tie to hold it in place and it works perfectly fine.
