Hi. Just picked up old school Peavey Grrind. J/P configuration, 3 band EQ,, Very comfy. However there is this most weird buzz that comes on the E string on 8th fret only. I already checked with fret rocker. No frets seem to be sticking out. This buzz almost sounds like TWO notes being played, and it disappears when I press ANY frets BELOW it when I play it. So, if I only play E string 8th fret - Buzz. If I play E string, pressing 8th fret and any other frets - 7th, 6th, 5th, whatever - no buzz. I already checked my tuners - they are tight. I already checked the screws that connect neck to body - they are tight too. The "ghetto fix" of putting a small tightly rolled piece of paper right against the nut on the 1st fret moves this buzz from 8th fret to 6th. with the same situation. Almost sounds like two notes being played. VERY unpleasant sounding.
Any ideas? Neck does not seem to be twisted, as this is the only fret affected. There is no obvious "ski ramp" as, once again the only fret that is affected is 8th fret on E string. I really like the bass, and I do not want to return it. Any advice?

Do you have another string to test with? There might be an imperfection. You may also have a wide nut slot that is causing some buzzing behind your fretting. Use something to mute the nut side of the string when you play, see if the issue persists. Admittedly, I am spit-balling here. I am not positive what your issue might be based on your description. I am also assuming you gave the bass a basic setup since you own a fret rocker.
