There is a spot on my Warwick thumb bass where the wood is starting to fray a little. It's on the neck, on the right-hand side (i.e. close to the G string) around the 3d or 4th fret and right where the fretboard starts. The grain of the wood comes up to little "V"-shaped points all in that area and the tip of the "V" is becoming exposed and bits of the wood are separating from the neck. I have actually gotten a couple of splinters from playing in the past week! You can't tell by looking at the bass that there is a problem, and even if I take my finger along the edge of the neck it feels basically normal except that one spot feels a little rough. I certainly don't want to keep getting splinters in my left hand, and I want to prevent the bass from just disintegrating. Will waxing the bass with the carnuba wax help? Or is this a bigger problem?
