Hey guys. First off, the equipment: Ibanez SR530 Bass Gallien-Krueger 1001RB-II Avatar 4x10 Cab Ibanez Jet Driver Distortion Pedal So I was playing my first show at a local bar with the band a couple of weeks ago and after the first song, the "sound guy" asked me to turn my bass up. The Gain was at about 10 O'Clock and the Boost (Master) was at about 12, as is recommended to be on 12 or 3 according to the manual for best results. Anyways, the other dudes did sound louder than I did, so I obliged and turned the gain up a notch to about 11 O'clock. As soon as I try to play the first note of the next song, my amp just shuts off. Thought maybe the surge protector stopped, but my 2 other rack mounted devices were still on (including my Furman Power Conditioner that the amp is hooked up to). Couldn't get it back on, so we decided to put me through the vocal speakers instead. Was a terrible night. Next day I opened it up. The fuse was blown, so I hoped it was just that. I put in another fuse, powered it up and it immediately sparked and blew the fuse. I don't get a red light for the power indicator either, just nothing. I bought the amp refurbished from GuitarCenter.com like 3 years ago so I don't think there is a warranty. I tried searching for an amp tech but I live in a really small town, and couldn't find anyone online. My guitarist said he knew a guy who fixes amps on the side though, so we let him take a look at it. My friend said that he said all 3 capacitors went out so he's going to replace them. I guess my concern is wouldn't there have to be a reason that the caps went bad? I thought they mostly only got bad with age really, like 20 years or something, and I can't imagine this Amp being anymore than 8 years old, at the very latest. I'm just afraid that he'll replace them and the same thing will happen again at the next show in 3 weeks due to something more. Was just wondering if anyone would have a better inkling to what might have caused it, just based on turning up the gain a bit more. Thanks!
