I have had a strange phantom buzz on my new G&L M2000 around the 10th fret, A string. for the life of me, I couldn't figure out the source. frets are plekked and flat, strings are new, relief is where it should be etc. the action wasn't terribly low like some of my other basses, yet I had this buzz. one thing I never checked- PU height. (I never did adjust it from the factory). it did seem high, and I know the MFD's are known to be powerful. I lowered them a tad and the buzz is gone; the PU's were dragging the string down a tad just enough to fret out. I should mention-it only happened when I fretted at the 10th fret; this brought the string really close to the pole pieces. anyone else have a similar thing happen? I thought I would pass it on because naturally, it was the last thing I considered.
