Well I did it. I have been debating about getting a fretless bass for quite a while. I really didn't want to get another bass,(I really cant justify all the ones I have now) so I decided to defret one of my P basses. I did it this last weekend and it came out real nice. I pulled the frets, sanded the neck and filled the slots with the rosewood sawdust and superglue. After I got it all sanded and level again I took a fine hacksaw blade and cut a slot at a forty-five degree angle at each fret for position markers and filled them with white wood filler. These extend from the thickness of the rosewood on the side of the neck to about a quarter inch long on the fretboard side just under the E string. Buffed with 0000 steel wool and a coat of Tung Oil. The neck looks great but I'm not really sure how to cut the nut for a fretless. Should it be cut as low as possible to try and match fingered notes? Any help is appreciated.
