Ochsenfree Posted July 7, 2015 Share Posted July 7, 2015 Hi all, My CMD 102p has started making an annoying buzz sound when I play resonant notes. It doesn't have to be loud to do this and only stops if I roll the bass off to 9 o clock or so. I'm using an American Deluxe Jazz, and as you can imagine it's a lot worse when the active switch is on. It's not fret buzz and I've tightened every single screw and nothing is moving. Using the DI into my PA it sounds fine, using external cab the cab sounds fine. Still under warranty but it's a 3 week minimum turnaround and I make my living using this amp! https://vid.me/HvG4 Anyone else experienced this? Thanks guys!

Marc S Posted July 7, 2015 Share Posted July 7, 2015 (edited) No real help, sorry I've had a CMD102P for years now and I absolutely love it! Great amp, great sound, and so lightweight Have you got any other bass playing pals, who would let you borrow another bass to try it with? That'd be my first option I know you think your bass is fine - but you never know I once had a lead which seemed to cause a bit of hum But it only happened with one bass - it was fine with another bass What's that all about? Good luck anyhow.... EDIT: Or even try a guitar? Edited July 7, 2015 by Marc S Quote Link to comment Share on other sites More sharing options...
Ochsenfree Posted July 7, 2015 Author Share Posted July 7, 2015 I've tried the bass DI'd through my PA setup. New leads all round. It's fine. I ran a sine wave (carefully) through the amp and it rattles from that. It's definitely the amp. Quote Link to comment Share on other sites More sharing options...
Ochsenfree Posted July 7, 2015 Author Share Posted July 7, 2015 Does it with my Upright Bass too. Quote Link to comment Share on other sites More sharing options...
