Yesterday I shimmed the neck pocket of my de-fretted Squier VM TB with a Stew Mac .5 degree angled shim. The bridge was bottomed out and I wanted the strings a little lower, so shimming seemed the right answer. While it did fix the issue of the bridge being bottomed out, I now have “dead spots” where the note sounds buzzy and choked out on the D and A string in the 17-18 fret range. It has a 2 barrel bridge, if that matters. Measured with my string gauge, all the string are nearly even height from the fretboard, at 1.75mm @12th fret. The only things I can think of are either the shim did something funny to it, or the fretboard there is more uneven than I thought...or the shims are making whatever unevenness there much more apparent. The bright side is that at least it’s way up on the neck where I nearly never play, so it’s not ruining any of my playing, but I would like to have the bass play well over the whole instrument.
