Sperzel Locking Tuners

Do you have tuning problems? Are you guilty of tremolo abuse? Sperzel tuners use a rear thumbscrew to lock the guitar string, eliminating tuning problems at the headstock. The string posts are staggered to increase downward pressure on the nut, thereby eliminating the need for string trees. Sperzel's feature a 12:1 gear ratio and sealed gears for maintenance-free lubrication. Threaded bushings and a rear pin allow installation without screws . Sets of 6.

Important dimensions:

• Fits 9/16" - 11/16" thick headstocks.
• 10mm (13/32") diameter pegholes.
