Most guitars are a few adjustments away from being great playing instruments. Even a budget instrument can feel like a custom-shop masterpiece with a proper setup. Most “unplayable” guitars suffer from geometry issues that are easily corrected with a few standard guitar adjustments.

Best Guitar Adjustments

Here are the key guitar adjustments that bridge the gap between a “stiff” guitar and a great one:
1. Neck Relief (The Truss Rod)
The truss rod controls the curvature of the neck to counteract string tension.
  • The Goal: A very slight concave dip with the strings under tension.
  • The Fix: If the neck is too bowed (dipped with high action in the middle), tighten the rod clockwise. If it’s humped and buzzing on the lower frets then loosen the truss rod counter-clockwise. Adjust in small increments. The tack hammer method is preferred over the sledge hammer method. 
2. String Action:  Bridge and Nut Height determine ease of play.
Action is the height of the strings above the frets so, the lower the strings are then the easier the guitar is to play.
  • The Goal: Comfortable playability without excessive fret buzz, pressure and finger pain.
  • The Fix: On electrics and acoustics the fix varies according to type of bridge. Tune-O-Matic bridges (Gibson style) have thumbwheels at the bridge to raise or lower the saddles. On acoustics, this typically requires carefully removing and shaving the bottom of the bridge saddle then replacing it back. Test and repeat as necessary.
3. Nut Slot Depth
The nut height determines how easy it is to press down strings at the first few frets
  • The Goal: Strings should sit just high enough to clear the first fret without buzzing when played open.
  • The Fix: If it’s too high, ask a good Luthier or great guitar tech with nut files to deepen the slots for you. Don’t forget to lubricate the slots to avoid pinching.
4. Intonation
This ensures the guitar stays in tune with itself as you move up the neck
  • The Goal: The fretted note at the 12th fret should perfectly match the 12th-fret harmonic.
  • The Fix: Move the bridge saddles forward (if the note is flat) or backward (if the note is sharp).
5. Pickup Height (Electrics but some acoustics fit in this category as well)
Pickups that are too high can cause magnetic pull that kills sustain or creates “warbling” tones.
  • The Goal: Balanced volume across all strings and clear tonal response with a good signal.
  • The Fix: Use the elevator screws on either side of the pickup to find the “sweet spot” for your ears for best guitar adjustments.
