Hoping someone can help me out with this... I have a Schecter stiletto studio fretless 4 string and LOVE IT! But it would look so much better if I could cover the fingerboard lines. If I need to look when hitting a particular rift, I'm looking at the neck edge not the face of the fingerboard. I tried a black Sharpie to cover the lines and it looked great. But it wears off fast. Has anyone successfully hidden fingerboard lines on a fretless? How? Thanks in advance !!
