Just about to install a new slotted Jazz Bass nut in my Fretless. Just wondering, Is it better to have the slots closer to the fingerboard? I play with a light-medium touch, and I want quite low action, but with the old nut I had it was buzzing like all hell before the first fret (you know what I mean). I'm assuming this is because of neck relief, but will it help to file the nut slots lower than usual? Thanks a lot.
