I have never had this problem with my bass rig before. There could be numerous reasons/variables that could have led to this, so I will try and explain everything as best as I can. Bear with me people. Last night I played a show in the basement of a small sized gig. Before I went on I noticed that the wall outlets aren't grounded. Okay, no problem! I got a furman in the rig so I'm not too worried about anything. Didn't give it a second thought. So it comes time to set up. I get my gear all set up and turn it on. I'm not using PA support but I don't worry too much because its not a sizable venue. I get stuck next to the PA speaker. Whatever, no big deal, I have never had a problem before. So I turn it on. I'm running: Ampeg svt 4 Bbe 362 sonic maximizer, Korg dtr 1000 into Ampeg b series 4x10 (2 eminence speakers installed) Ampeg b series 1x15 (eminence speaker installed) with a Warwick Corvette Sansamp BDDI Bass driver Turned her on and... Nothing I got a deep bass sound as feedback from my speakers. My mute light and limit light were solid. I had checked the cables and the way they were hooked up and everything was fine. I have no idea what happenned??? I turned it off and hooked up my 4x10 alone without the pedal. FINALLY, I get some notes. However I was still a little po'ed because I couldnt use the 1x15 or my pedal. The sound wasn't very loud and my limit light kept coming on before I could get a decent volume. So I am looking to hear some reasons why possibly my rig F***ed up on me. It has never done these things before and I am really surprised it did. I would really like to hear the opinions of some experienced folks here! Thanks!
