Neck and Truss Rod
hand thumb (where the neck and body meet, typically around the 16th fret). Then, stretch your picking
hand index finger as far as you can to fret the middle area of the neck, somewhere around fret --. The
distance your string travels to meet the fret is the bow. Peavey recommends a . mm to . mm (.010” to
.020”) bow, easily measured and set with a steel rule. Too much bow leads to buzzing in the middle of the
neck because the strings are too far away from the frets, while too little bow (backbow) causes excessive
buzzing on open notes and notes near the nut.
To make adjustments for neck bow or relief (backbow), adjust the truss rod in 1/ turn increments, and
then recheck. If your neck is backbowed, loosen the truss rod by turning it counterclockwise. If it has too
much bow, tighten the truss rod by turning clockwise. Remember, a little truss rod adjustment makes a
big change in how your guitar plays. Improper adjustment may damage your neck and void your Peavey
warranty.
