About a year ago, I got my SX fretless, and it came with flat-wounds, which I didn't like. I recently switched over to some new round-wounds, which feel much better
. I've also been trying to lower the action a bit so I can don't have to push down that far (also to try and get a bit more "mwah"). This is the problem. At the moment, my action is different between each string. The G string is about where I want it (maybe 2 mm above the board), and the lower strings are each progressively higher, with the E string being about 4 or 5 mm above the board (I measure right at the end). If I go any lower on the strings, I've a really annoying dead spot between frets 6 and 8. I'm pretty sure the reason why is this: it's a lined fretless, and around many of the fret lines, the line or the finish (can't tell which) is slightly raised, and causes the dead spots. My 8 fret is definitely the worst offender, but I was just wondering how hard it would be to sand down these dead spots.
What grit sandpaper should I use to do it? And also, is it more trouble than it's worth (i.e. will the round strings do this of their own accord for me)? If I did it, I'd probably have to patch up the finish on the neck, which would probably take time.
