fretless neck - buzzing twang vibration at A note on the D string

[tortburst]

I made this video to show how this one note causes a buzz. It’s the A note, fifth ‘fret’ of the D string

Would this be considered a dead note or a wolf tone?

If anyone has advice on what to do about this, if anything, please share.
If it were an upright bass I’d bring it to a luthier to shave the fingerboard flat.



It’s a Fender fretless precision neck from 1978. I love the shape of it but would like it if it didn’t make that sound.

Thanks!

You probably have a bit of a hump on the fingerboard. The way to deal with it is the same as with an upright bass - levelling the fingerboard.

Wolf tones and dead spots have to do with specific frequencies that are either emphasized or absorbed by an instrument. This is neither.

First make sure there isn't a defect in the string at that spot. If not then you need to level the board.

The string is ok

I’ll have it leveled. Thank you!
