Hi: I recently got an MTD Kingston fretless five string bass. I love the bass but wonder if mine may have gotten a mediocre fretboard finish. It seems all the inlaid fret markers are very slightly higher than the fret board. This leads to a bit of string buzz when passing over a marker, such as when sliding between notes. I wouldn't think this is an optimal fretless fingerboard finish. I have adjusted the truss rod for a nice slight neck relief and adjusted the bridge saddles for medium-low action. Have any other Kingston fretless owners here experienced this and had the situation corrected in some way?
