I decided to tinker with my 30+ year old crappy Harmony acoustic. Started by using a razor blade to scrape the accumulation of dirt off the fretboard. When it started to take off some of the finish, I said screw it and kept scraping. Ended up looking like this: You can see the original color (and dirt) on the 12th fret. I don’t care if I screw up this guitar, so what do you think I should do to the fretboard? Leave it as is (I kinda like it)? Tint it? I don’t really have a specific goal with this guitar - just figured I’d tinker with it and maybe learn something as I do.
