A setup adjusts neck relief, string height, nut slots and intonation so the guitar plays comfortably and in tune.
Signs to watch for:
- Strings sit high off the frets, especially near the nut.
- New buzz on some frets or strings.
- The 12th-fret note is noticeably sharp or flat compared to the open string.
- The neck looks visibly bowed when you sight along it.
- Tuning drifts after bends or for no obvious reason.
Common triggers:
- Changing string gauge or tuning.
- Moving to a different climate, or seasonal humidity swings.
- A new guitar that traveled through shipping and storage.
Some adjustments, like intonation and saddle height, are approachable at home. Truss rod work and nut slots are worth leaving to a technician if you're unsure. A good setup often helps playability more than any string change.
