Let me start off by saying that plugged in, my bass sounds just how I want it to. Throaty, deep, grumbly. But when I strum it and it isn't plugged in, there comes a rattling from somewhere. I think it's the neck. Not sure. I'm also having problems adjusting the action. I've tried everything I can think of, and I can't really notice it. I know for a fact that the neck is bowed, because the strings are alot closer to the neck at the first fret that at the twelveth. I tried adjusting the tension rod, but I couldn't. Screw wouldn't budge either way. Do I gotta get a new neck, or what?
