So I just got an MXR Carbon Copy delay and I'm having some weird issues with it. From the momentr I turned it on I got a thud like sound that started to repeat with each repeat getting louder and louder until it nearly blew out my speaker. I figured it might be a problem with a patch cable/power supply/etc so I triple checked those things and they were fine.

I turned the pedal back on and it didn't happen but from the moment I hit a string the same thing happened. The sound is not a 'natural' type of repeat or echo and sounds absolutely horrid. Is this a defect with the pedal? I tried playing around the knobs and it would appear to be fine but without fail, it would always do it within 30secs.

Do I need to return it.

Turn the regen knob down. What you're experiencing is oscillation and it's awesome, when used right.

Yeah this.
