I was curious, if I were to sand down the back of my MIJ 62RI Pbass, is it going to affect it's resale value substantially? The bass already has some wear and tear, so I don't think anyone would be buying it for it's pristine beauty. Also, I did a quick search, but could someone point me to a thread detailing how to do this? My neck is extremely glossy and I prefer more of a matte/smooth finish. I am thinking you just tape up the strings, rub it down with 0000 grit sandpaper and possibly apply some tungoil? Thanks a bunch for your help, I realize this topic has been covered a lot.
