Hey guys, I've picked up two guitars this year with maple fretboards and pearl inlays. It looks fantastic, but they're also impossible to see. Apparently I'm a little bitch and need fretboard markers to figure out where I am, lol. Has anyone purchased any fretboard markers that don't mess up the fretboard/get super grimey over time? I've done some googling and amazon has several brands for not much. Just wanted to see if anyone has done this before, as it seems it'd be a common/easy mod. I've also considered glow in the dark tape, just don't want residue if I can help it.
