My bass makes three kinds of bad noises! Firstly, it's a Squier Jazz, which means poor build quality and (my first complaint), soloed pickup noise. I know that's pretty normal, so I won't make a big deal out of it. My two other bad noises are 1. What I call static. It's white noise that quits when I touch my knobs, control panel, bridge, strings, or tuners. (sure seems like a grounding problem, but I wanted a second opinion.) 2. My output jack seems to be giving me problems. First, it crackles(like a bad cable, but I've played through many cables on this bass, and many amps for that matter.) Second, it seems to affect my tone control. What I mean by that is, I'll have my tone rolled full off, but sometimes I'll move( i.e., wiggle the cord), and my bass will quite obviously sound like someone has rolled the tone knob full on (only lasts for a split second, when I'm shifting my weight or something while standing). Oh, while I'm here, my controls aren't very knob-like. They seem to be either full on or full off, there is a little in between, but not what you would expect from knobs. Basically, my pickups behave more like selector switches than volume controls, and my tone is more or less an on and of filter kind of thing. Is my preamp just totally wrecked or what? I'm worried because when I play through my new amp it will make nasty loud noises sometimes for one/all of the abover reasons and I'm afraid it's killing my amp.(no signs of that yet, but I'm a hypochondriac).
