To identify whether your PRS has non-locking tuners, your guitar’s tuners will be missing a cap screw on the tuner shaft, and the shaft will have a solid top.
How to Restring Non-locking Tuners:
- Remove old strings.
- Turn the tuner buttons until the hole in the tuning peg is pointing at the string’s nut slot.
- Pull string through hole and over two fingers (or 1.5”) at the nut. (Actual slack is approximately 5/8” to 3/4")
- Bring the end of the string towards the truss rod cover and back under the taught string.
- While continuing to pull tight, bend the string back over itself so that the string locks in place when tightened.
- Turn the tuner buttons to bring the string up to pitch, making sure each new wind is under the previous string’s coil around the shaft.
- Clip excess string.
Proceed with setting up your PRS, checking and setting relief, action, and intonation. Always thoroughly stretch new strings during setup to prevent tuning issues.
