I was thinking of converting my "backup bass" to a fretless. For those of you who know me, I will not be doing this myself, so don't start. Here's my question. I have a Cort B4, for those of you who don't know the bass, that's a ash body, wenge neck, rosewood fretboard, pretty basic bart p/ups, 3 band EQ. I recently went to a six string, and I don't play a hell of alot of four anymore, So I was thinking if it'd be a good idea to rip the frets out of the little mongrel, seeing as all I use it for is jazz, blues etc. where the six string is just excessive. So my query is, what should I do to the fretboard if I do defret, cause I heard a rosewood fretboard can get eaten pretty quick.
