Hey I've just recently put the cool rail (neck position), vintage rail (middle position), and hot rail (bridge position) into my Texas Special strat and I'm just lovin' the tone...flexible as hell. However, I also own a blues deville 4X10 amp that I just re-tubed in the spring and all of the sudden I'm hearing this ugly crunching sound when some frequencies are played loudly on my guitar. It seems the volume consistently decreases by itself as well at times when playing for a while. This really makes everything sound like ****, so I was wondering if anyone knows maybe what the problem might be? I've left my amp in my car at times when it can get real real hot in the car..does that have anything to do with it? It seems the input jack on my guitar has also been a little loose lately but doesn't seem to pose much of a problem itself. I was also wondering if anyone knew of compressors that are better than those made by BOSS. Thanks a lot.
