Last night at a band practice where I play drums and the bassist uses my rig, we started to hear a horrible bussing from my amp! It's only when you play, and it's only very noticable at quieter volumes, but it must be some kind of distortion as there's no noise when you're not playing.
Because of the recent failure of my trace 18" extension cab (see other thread, still not fixed) I have been running my combo a bit louder than I used to.
Also, because of the recent purchase of a barge concepts blender, i've had a slightly less compressed signal recently.
So, i'm turned up louder, with louder peaks to the input. The yellow DDT light has been comming on in most of the choruses and riffs for my band, where i'll use my loudest settings.
I did read on here that the Peavey DDT system was really good and effective, so I wasn't so worried, but, now i'm hearing this horrible distortion!
What could be causing it? What could fix it?
Basschat caused the less compressed sound and caused me to trust the DDT so now basschat owes me a fix!
Thanks in advance
EDIT: I just noticed the "humming and buzzing" sticky and wanted to make clear - If I play just my bass, or just an electric guitar with humbuckers through two different planet waves leads, no effects or anything, straight into the amp, I still get the noise.
