Hello all, got a question for you. Lately, I've been doing some playing with my Crate BX-100 and sometimes after I've been playing awhile, this loud crackling noise comes out of the speaker. At first I figured it was dirty pots or something, so I spun all them around, pressed all the switches, etc. No change at all in the crackling. Thus I figured it was the cable, so I unplugged the cable and yet the crackling remained for about a minute or so before it died down! Even if I turn off the amp and then turn it back on, I can get it to crackle again by playing certain notes (seems like A and D get it going the worst). Turning it off immediately stops the noise, but if I turn it on again and play either an A or a D then it starts all over again. I can't for the life of me figure it out. It also doesn't seem to happen unless I've been playing for awhile (45 minutes at least - and I practice at low volume; about 2.5 to 3 on the volume). If the speaker was blown, then I'd get the crackle no matter what right? And plus, if there is no input (i.e., no cable even connected to the input), then it shouldn't be producing any sound anyway. Normally, it's dead quiet with nothing plugged in and almost as quiet when I plug my bass in (I sometimes get a radio station in the background, but it's not very loud). Any suggestions? Let me know if there's any other information any of you might need. Also, I've only owned it a couple of years and I've really babyed it - so it's not like it's seen hard use or anything. Thanks.
