Hi all, I recently purchased a Harley Benton Beatbass, which is a Höfner style violin bass. I put brand new 50-100 Labella flats (760FHBB) on the bass and set it up. Then i realised that the notes are flat on the E A D strings at the first 3 frets by 8-12 cents, the E string is the worst. The intonation is OK at the 12 fret (even sharp a bit). The neck relief is .012 over the 8. fret, my action is 2.6-2.0 mm at the 17. fret. I filed the nut slot to have a better break point to shorten the string (close to the end of the fingerboard as close as possible) I also tried to compensate at the bridge and move it toward the headstock and so it became sharp at the 12. fret but on the first 3 frets it was still really flat. Before that i had the opposite problem with other basses and guitars when the notes were sharp because of the high not, but in this case what's wrong?? Thank you in advance.
