I have always liked bound fretboards. To me, there is something about a guitar with a bound fretboard that says "this is a high-quality instrument, someone has taken a lot of trouble to get right". To be rational though, I can't think of a single good reason to put binding on a fretboard (other than mere decoration). I never feel any difference while I'm actually playing.
So is there a reason? Is there any practical benefit in a bound fretboard?
