I play a Fender Marcus Miller Signature Jazz Bass that has had some ski-jump neck issues (frets 15-18. In the past I have used Fat beams 105 80 65 45,; Hibeams 105 80 60 45 (presumably close to balanced). At the point that the ski jump issue cropped up, it required extensive fret filing & leveling, & I was advised to go lighter with the Hibeams 100-40. So far no more ski jump. I have noticed in times of fluctuating humidity (in the Dessert) the TR needs tightening some day, loosing others. Howevrr, it seems that I tighten a little more than loosen, indicating it might be maxed st dome point. ould going lighter, say 100 75 55 40 make for greater stability? One advantage for those gauges is closer to balanced, but how about stsbiliy, & fewer TR adjustments?
