I have taken out FOUR amps this week. I am not sure how this is possible. It's not my house wiring, since the Fender was at Tim's house, and the Peavey combo at Sean's house when they blew up. Tuesday: Fender Bassman 400 blows both speakers. I didn't even have the volume up to 5, and no clip lights were on. Good thing I've got four backups! Wednesday: Get my Peavey Mark 3 head set up, plug in, play for 10 seconds, and the inputs go dead, then make horrible buzzing and squealing noises. Well, that sucks, but I've still got three amps, I'm good! Thursday: Old Peavey 1x15 combo. Amp develops a short somewhere inside. Keeps blowing fuses. Man. This is not good. Friday: Bass Pod (borrowed) and a generic power amp. Play for maybe half an hour, and the amp begins to make this horrible high-pitched squealing, both clip lights come on, the volume knobs stop working, and that's done. ... Now, I've still got a Peavey Databass. I also have practice tomorrow evening. Should I risk this amp this week or is all this a sign that practice should be cancelled? I ask you for guidance, Internet!
