Took a while, but I finished sanding the fretboard nice and flat. I wanted to see if I could do a setup...but realized there were two problems with that idea. The first is that the tapewound G string broke. I have now had two sets of tapewounds. The first was from Fender. One day I accidently knocked over the bass, which landed on its face, and broke the A string. Thinking that the Fenders were not durable, I got D'Addario tapewounds. More of an upright sound, but same durability problems. Setup is on hold until I can get some steel flatwounds. So this seems to be a general problem with tapewounds. It's very easy to damage the tape, and the string is totally useless once you do.
The other problem, I realized once I got out my truss rod key, is that I have on idea how to set up a fretless bass. I use a feeler gauge between fret and string on a fretted... not sure the same logic applies with a fretless? Anyone know a good reference for this?
