I just bought a Peavey 115 Black Widow cab to go with my T-Max combo and when I hooked it up it sounded like wind blowing through it! There's no popping or anything and when I turned it up the sound is ok. Other than the loud hiss! I tried unhooking my effects processor and just playing through the amp and I got the same thing. The speaker cord is brand new and a fairly good one so I wouldn't think that was the problem. This is my first cab and I hope there's nothing wrong with it because I don't want to ship the big a@@ thing back! Any suggestions on what it is or some trouble shooting I can do?
