I recently removed my neck on my MIM 60's jazz bass because I was having problems tightening my truss rod. So I removed it and made an adjustment, but after I screwed the neck back onto the body I'm finding that I have to raise the string height almost all the way up just to get the lower 6 frets to stop buzzing. There seems to be some slight relief (like there should be) so I'm not sure why I needed to adjust the string height so drastically. I always do my own setups, and I have that part mastered. Did I re-install the neck wrong?? What could causing this problem?? I would like to avoid taking the bass to a shop obviously.
