BRIDGE/SPRING TENSION ADJUSTMENTS For best results the bridge should always be adjusted so it is parallel to the top surface of the guitar as shown in illustration (below). This position is maintained by opposing tension between the strings and the claw springs. If you change string gauge, you will need to readjust the spring tension to return the bridge back to the parallel position. The adjustment procedures are: 1) Remove the screws that attach the tremolo cavity back plate from the back side of the guitar exposing the claw springs. 2) Make sure that the guitar is tuned to proper pitch. 3) If the bridge is tilted forward (up), tighten spring tension by turning the claw screws clockwise. If the bridge is tilted back (down), loosen the spring tension by turning the claw screws counterclockwise. (illustration - A) Be sure to check string pitch after each adjustment to the spring tension. A A 8 Adjust the height uniformly using the two screws A. @F@H@PN@FOJOEE
