I am also a member of the stupid buzzing zr club. I thought it was my strings pinging on the frets, but it didn't come from the
fret board. I thought it was the springs, so I insulated the whole cavity with a cut up coozy. I thought it was the fine tuners, so I loosened them all the way out and shoved some strips of coozy in there and tuned them back to normal. Nothing really helps except baisically
palm muting the trem. Also, hub, nice tip on lubricating it, but u love ur trem too much. Maybe the 08 hybrid zr's won't have the buzzing problem.
