I have been searching here on TB and other places, and am surprised that I haven't found this answer yet. What are the indents on the high end of the fretboard for? The ones under the D and G strings. I have read numerous interviews where he talks about his bass, but none where specifically mentions those indents. The only thing I could come up with is that they are used as an alternative to bending the strings, he just pushes down harder and get's the desired effect. Or are they just for looks?
