Hey guys,

Just got a used Behringer DD600 from eBay, nothing special was just looking for a cheap delay pedal before i can afford a better one, but there is a problem. When the pedal is plugged in there is this washing machine like sound that doesn't stop and its really annoying!

Anyone know how i can get rid of this/had the same problem?

Its not too bad when its on and i'm playing, so maybe i can true bypass it for the mean time?
