I was told that this would be a good post to ask Myles about. I have owned a b-52 AT 100 2x12 combo for a couple of weeks and I have recently noticed a strange deal. On any string, C notes seem to have an odd hmmm, a kind of raspy? sound almost like interference that lasts even shortly after the note fades, kind of staticky. Sounds pretty bad but it stops when I mute the string. I can only get it to make that noise predominant on that note, its not apparent at any other. It increases proportionate to volume and seems louder and over the top of the actual note and happens on any channel or rectifier setting. Comes in right after the note and lasts longer than the note sustains, weirdness.It was a floor model, I dont know if that has anything to do with it being possibly abused. This is my first tube amp and I love it aside from this problem. I could just take it back but its like 100 miles one way to GC. Its within 30 days and on top of that I have like 7 years of extended warranty that I bought hoping this would be the only amp I would ever need. Could it possibly be a power problem in my house that I wouldnt be able to tell from any other device in my house? Any way to test for that, meter etc? I did have a solid state amp before here and I never noticed a problem with it. I live remotely and its tough to get any of my buddies to come around and observe it with me and I dont know if they know much about tubes either. Any help is greatly appreciated.
Edit: Tried it with a LP studio and a Jackson, same prob and 2 different cables, same stuff.
