Just picked up a new (to me) '94 Wasburn XB-500 5 string with "active electronics". I love the tonal range I can get, but noticed something the other day that bothered me. I'd be tuning one of the 3 lower strings and my meter would register "right on", but when I let go of a tuning knob, the needle would register a bit flat. Yes I may have been pressing down some on the knob. If light hand pressure tightened the string and taking it off, loosened it, wouldn't that indicate the neck is not tight to the body? If so, what's the best way to deal with the problem? Get out a screw driver and torque away, or is it more complicated than that?
