1. Locate the adjustment point on your guitar.
On acoustic guitars its generally in the soundhole, while electrics and basses are located in the headstock just above the nut or at the base of the fretboard.
2. Loosen the 3rd and 4th strings. Pull them to the side and remove the truss rod cover if applicable.
3. Holding the neck at eye level, sight down the neck to see how much of a hump or bow it has taken on both sides.
5. Tune your guitar back up to pitch and see if the action is at a comfortable playing position for you.
Be sure to avoid over-tightening of the nut. Failure to do so can result in stripping the nut or breaking the truss rod.
If you have any questions or don’t feel comfortable doing this on your own, feel free to call our tech or take it to your local luthier for guidance.
