I just took my bass out for the first time in a while, and I was just reminded about how upset I am at the performance of my Ampeg SVP-Pro. I'm a college student without much money, but I need a new preamp if I'm going to start playing bass again. I have an SVP, and it #1: sounds great, #2: emits a huge ammount of static noise (don't even think about trying to record with it, or staying sane sitting anywhere near the amp when it's on.) and #3: stops working properly periodically, and just emits an extremely weak, crackling signal. For some really weird reason, adjusting the tension of the screws on the rackmount makes this come and go away. I know, it makes no sense, but I am not making this up. I've replaced every tube, and taken it to the shop (they said it was one of the tubes and they replaced it, but it still suffers from these 2 problems.
