I just turned on my rig (trace ah250 + Genzbenz 2x10xb cab) and There is a steady buzz coming from my horn. It happened as soon as I powered my amp on w/ the amp still on mute/standby, before plugging in. I tried a different bass and a different cord...still buzzing. Is it possible it is my head? I noticed the fan came on as soon as I turned it on which it usually doesnt. I dont have another amp here To test the cab with. I will try another cab, I just didnt feel like lugging my 15 out of the basement. Does anyone know any obvious issues that would cause this? Or any suggestions to isolating the culprit?
