well, im sick of my head. its a crate turbovalve120, it seems like i can never get a sound i like out of it. im using a metalzone with a boss equalizer,(the stock distortion channel sux) but i still never like the sound, its either too much bass, and making my speakers puke, or not enough and palm mutes sound like shit.new preamp tubes might clear that up though, i noticed one of them is burned out. anyway, i was thinking about going to a rocktron gainiac pre amp, with some power amp(my cabinet holds 800 watts, room to expand), just wondering what you guys think about rackmount.the way i see it, when i get more money i can add on alot more to it to make it even better
