Hello! Ran into a snag and now I'm turning to you guys. I recently purchasef my first amppeg Svt 350 with a Bse 410 hlf Cab. I love it, brought it home today and had a good time. When I went to go shut it off I noticed the Amp itself was humming. Not going to lie it was plugged into a power strip. So I plugged it directly into the wall and same sound. Its not loud and it doesnt increase in volume when I play. Just never heard it before. I dont know if I should br alarmed or where I go from here. Any help would be apreciated.
