I recently bought an SX fretless to play around with, and although I like flats I'm wanting more zing and growl out of that bass. I don't want to go through the work of coating the fretboard with epoxy or paying someone to do it since it's a cheap bass and I only use it to fiddle around with on occasion (like an hour or so a week, just for fun). Would I be fine putting rounds on it in that case? How quickly would it eat the fingerboard? Would a coated string such as Elixers help any or is the coating too thin to make a difference?
