Tell us if You have, let's say, a Fender player jazz bass - defretted and refinished. Did You ask Your luthier to do it, or bought allready modified, may be did it Yourself? Are You satisfied with the modification. Tell more about it and somes pics would be great, too ! Mine is - Fender Jaco tribute jazz bass - fretted and refinished to black. It was hard for me to play it fretless, but the instrument was so great, it sounded superb unplugged and i didn't have any fretted bass, so i asked my luthier to fret it and he did it perfectly. Another guy who was a specialist in refinishing, made it black. I love how it sounds and looks.
