I recently bought a very nice J bass neck from Warmoth. I've given the neck to a local guitar repair guy to install fretlines. The neck came with no frets but the slots are cut. I really want fretlines that show up in dim light so I'm thinking that the maple strips that are normally used might not be light colored enough. Or that they might darken up over time. The guy says that the material that is used for fingerboard binding should fit in the fret slots. Do you think that this would work out ok? I have no experience with this and apparently neither does he.
