Observe the distance between the top of the 5th fret and the bottom of the string. This gap indicates the amount of relief.
Using a 4mm allen wrench, adjust the truss rod and then check the relief until you have a gap approximately equal to an index
card. Tightening the truss rod will reduce relief, loosening will increase relief.
Relief can be affected by changes in climate. High humidity will reduce or eliminate relief, low humidity will increase relief. The
truss rod may require adjustments during seasonal changes (fall, spring) or any substantial change in climate.
2) String Heights
Numbers represent 64ths of an inch, measured from the bottom of open string to the top of the 12th fret, with the instrument
tuned to pitch and held in the playing position.
3) Pickup Heights
Numbers represent 32nds of an inch, measured from the bottom of open strings (two outside strings) to the top of the pickup
pole piece. Pickup height can radically change the tone and volume. On some models, individual pole pieces can be adjusted to
change individual string volumes. We recommend you experiment to suit your personal tastes.
