I like the concept of this amp. I like the sound it produces, too but it cracks, snaps and pops, and it's driving me crazy. I was in my studio attempting to practice and the noise this thing makes is maddening. Anyone else using the Hartke LH1000 or any other amplifier have this problem? I'm writing this in anger over this thing. I want to throw it through the bleaking window because it's freaking NOISY!!! There, I got that off my chest. Any suggestions?
