I currently have a 210 and a 410 cab. I only use the 410 cab for larger gigs. At my last gig where I used my 410 (Peavey 410 TXF), my speakers sounded very distorted and scratchy...even at lower volumes. I thought my speakers were blown (because it sure sounded like blown speakers). What puzzles me is that it was intermittent. We checked my bass, my cables and all speakers connections and could find nothing wrong. I have it at home and all the speakers are out of the cab. I checked each speaker for tears everywhere. No tears, or any signs of stress or physical problems with the speakers themselves. They all move freely and I did the battery test on each one individually. I've never driven this cab very hard, and never clipped my amp. Here's what I think is the problem. Before I joined this band, my cab was sitting (covered) in my garage for about a year, unused. The Peavey cab has a built in crossover and tweeter with an attenuator. The 1/4" jack is wired through the crossover. I think some part of the crossover is corroded. I haven't verified anything yet, but I was thinking of using a blank jack plate and a new 1/4" jack and wiring the speakers back up directly to this new 1/4" jack and bypassing the crossover and tweeter completely. I pretty much had the tweeter turned off anyway. I'm thinking that if I just disconnect the tweeter, and connect the speakers directly to a new jack, that this intermittent distortion and scratchiness will go away. Anyone concur, or think differently? Anything else I could check?
