Re: unfinished leather guitar straps
i'm with GJ...nylon is the best IMO. planet waves are nice as are the dunlop and levy's but i must say, my favorite strap i own is a red dimarzio nylon strap. for some reason it's just a nice comfy strap that is well made with nice ends and smooth nylon. i'd try some form of good quality nylon strap beofore you mess with the leather one.
