Members Beasleyboy Posted August 23, 2009 Members Share Posted August 23, 2009 I just picked up a MXR Carbon Copy a couple of days ago and I'm running it in the loop of my Mesa DC-10 after my MXR 10-band. My amp is almost dead silent until I click on my Carbon Copy and I get a ton of hum and a whirling noise (I tried all different settings and it's the same on all of them)...is this normal or should I exchange the unit for a different one?

Members delayed delay Posted August 23, 2009 Members Share Posted August 23, 2009 Do you have the mod on? What are you using to power it? If the answer is yes to the first question, that's where some of the whirling noise is coming from... but it shouldn't be that loud. If you're using a cheap power supply, that may have something to do with it as well. But regardless, you shouldn't be getting that much noise from it. I never get excess noise with mine. If you're able to, exchange it for another CC. But whatever you do, don't give up on the Carbon Copy, it's an amazing pedal. Also, analog delays in general put out SOME amount of noise; that's the beauty of it. And the whirling noise will make you when you're really able to see it's potential after getting rid of the hum. I recommend powering it with either an MXR power supply or the PP2+. EDIT: Most FX loops are gonna give you hum, that's just a fact. And I've heard quite a few people complain about hum in FX loops in Mesa amps. Link to comment Share on other sites More sharing options...
Members Beasleyboy Posted August 23, 2009 Author Members Share Posted August 23, 2009 Thanks for the info. The thing is there isn't any noise with the loop until I activate the carbon copy. I'll try a different power supply and see if that helps Link to comment Share on other sites More sharing options...
Members OldCrankyDouche Posted August 24, 2009 Members Share Posted August 24, 2009 Wasnt there a thread about the Mesa FX loops and analog delays? I swear it was around earlier today. Link to comment Share on other sites More sharing options...
Members ben_allison Posted August 24, 2009 Members Share Posted August 24, 2009 Analog delays can produce noise AND super high-pitched clock noise/whine. My experince with the CC was that it was not too bad... not very audible. Link to comment Share on other sites More sharing options...
Members Beasleyboy Posted August 24, 2009 Author Members Share Posted August 24, 2009 I just tried out a different power supply. That definitely is the issue here, the hum disappears with the new power supply. Thanks for the help! Link to comment Share on other sites More sharing options...
