I bought an Explorer knock-off recently with a bolt on 24.75" 24 fret neck. I had replaced the plastic nut with a Graph Tech (done it many times with a 100% success rate). Well no ones perfect I guess, there was a lot of string buzzing when I hold the 1st fret on the high E & B. I thought I set it a little crooked so I pulled it off, filed the glue off, and reset it. Now there is buzzing on all the strings at the 1st fret. I thought to myself 'I really like this guitar, I REALLY don't want to f@ck it up doing something stupid'. I called a local shop and they said a setup w/ bone nut would be about $150. OK. I started doing bridge homework on a guitar I'm going to make and saw that Gibson uses top mount T.O.M.'s to offset their angled necks. It was said that a top mount T.O.M. wouldn't work on a Strat because it has a straight neck and the strings would be too high. Well my "Explorer" has a top mount T.O.M. AND a straight neck. Would that be the source of my buzzing or is it unrelated. If all I have to do is get my router and knock the bridge down 4mm (I measured my LTD M-50) to fix the problem that would be awesome. I'd save $150.
