The practice of sighting down the neck to see whether there is a bow or bend is unreliable, and even experienced bass technicians can be misted by optical illusions. A better method to check for proper curvature is as follows: Step 1: Tune strings to proper pitch, and depress the strings by placing a capo directly behind the first fret. The capo should be just tight enough to effectively create the tone of F when plucking the E string. Step 2: Depress the E string directly behind the 16th fret with your left hand index finger. The E string depressed at opposite ends of the fingerboard acts as a straightedge, allowing measurement of the space between the fret tops and the E string. Step 3: Measure the mentioned space at the 7th fret by inserting the appropriate feeler gauge blade (right hand). (Move the saddle closer to the neck) Octave adjustment screw If the pitch at the 12th fret is flat compared to the harmonic tone Turn to the left (counter-clockwise) If the pitch at the 12th fret is sharp compared to the harmonic tone Turn to the right (clockwise) 8 Angle Adjustment for the Tremolo Unit Adjust the spring screw, located on the back side of the guitar body, so that the tail piece section of the tremolo unit is parallel to the body. If the string gauge or the position of the spring hook is changed, adjustment of the tremolo unit's angle (adjustment of the amount of floating) will be necessary. Tail section 1. Adjust the four (4) cover fixing screws located on the back side of the guitar body and remove the cover. the two (2) spring screws uniformly, so as to maintain good balance, and adjust so that the tail section is parallel. · If the tail section is raised Turn the spring screw to the right (clockwise). · If the tail section is lowered Turn the spring screw to the left (counter-clockwise). Adjust the height uniformly 3. Adjusting will affect string pitch so please check and tune the strings after adjusting the tailpiece. Spring Screws Springs Adjust equally. 9 Adjust the Arm Tension Use the tension adjustment screw, located on the side of the tail piece, to adjust the tension that holds the tremolo arm in place. Insert the supplied Allen wrench into the tension adjustment screw on the side of the tail piece, and adjust the tension that holds the arm in place. Turn the Allen wrench to the right (clockwise).
