I have a little problem with my amp (ashdown abm 500 evo iii). Actually, I think its more a problem with the current circuit in our rehearsal room, but I'll come to that later. The problem in the first place is that the amp sounds really really fuzzy.
However, the DI-signal (pre-eq) sounds completely clean!... So I went to my local music store (with all my gear; ABM 410 and 115, effects pedals and bass) for several times and tried to show them the problem, but the amp always worked in the store.
After I tried out some other locations (my apartment, e.g.) I'm pretty sure that there must be a problem with the power supply in our rehearsal room. The problem is not entirely new. It was the same with my ashdown mag c210 combo... Funny thing is, that it only appears during wintertime. Do you guys have any ideas about my problem?
I don't know if this is relevant for the whole "current circuit thing", but I'm from Germany.
I hope my english was good enough to give you an impression of my problem.
