I bought a G&L L2000 Tribute bass, which is great except for the fretwork. I couldn't seem to get the action low enough without buzzing, even after setting string height and adjusting the truss rod. I also had some frets which were not seated correctly at the ends. So, I decided to pull the frets and refret with shorter vintage type frets. I used my fret puller, cleaned out the slots, installed the new frets, cut the end with my fret cutter, leveled them with a radiused sanding block, recrowned them, beveled the ends, and sanded everything smooth. I still buzzes in the upper frets and still can't get the action right. I even used a metal "fret rocker" to find high frets, but they're all level. I've decided to pull the smaller frets and reinstall medium jumbos. I also have a fretting saw on the way with a 0.22" kerf to almost match the tang width. How do I work the fretboard and install the new frets so that I can get low action and no buzzes in the upper frets? Thanks!
