I have an Ibanez RG340(or whatever model)... passive humbuckers...

Im getting an echo-like hollow sounds from my amp right after I finish a chord, or playing anything really..

at first I thought it was my amp... I switched amps, and same problem.... Im not sure whats causing that added noise...

Im missing a height adjuster screw on the mounting ring... Is this the problem?

If the guitar has a trem, it is probably the trem springs. The springs vibrate with the body and the body's vibrations cause the coils of improperly-potted pickups to vibrate as well, creating microphonic properties that are heard from the amp.
