Chasing a buzz

[Doug Davis]

when I talked about trueing the board, I was referring to making sure the relief or scoop in the board in constant rather than wavy, uneven, or had low or high spots.

It sounds as though the fingerboard just isn't shaped right. Since it is maple (and probably way to thin anyway) I wouldn't waste time making it thinner still - a new, properly shaped ebony fingerboard will make a big difference in the sound and playability of the bass.

yes, I basically started from zero again and made sure that the relief arc in the board was a fair curve with no bumps or pits, by block sanding with a small enough block, then using a block file.

this seemed to work well.
