I'll start off by calling myself a jackass for this one. When I got my SKB case I was a bit worried of geting the cables messed and tangled up so I looped the speaker output cable to an open hole, in this case the foot switch imput. Upon firing the amp up I noticed there was no sound but everytime I hit a string the OD light would flicker. After a few seconds I checked and realized I was sending a powered signal to my my foot switch. I quickly shut it down and pluged the speaker cable to my cab where it belongs. Everything sounds fine clean but I do not have OD anymore. Is this just a fuse or did I fry some of the inards? I'm afraid to take it in for the cost of repairs. Please help!
