Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Designed to set the standard for closed tuners, all parts are CNC-machined, surface-finished, and fitted with a self-locking drive for smooth and consistent performance.
Crafted with premium brass string posts precisely fitted into the housing, these tuners ensure lasting stability and wear-free operation. The innovative stepped M6 flanged washer centers the string post securely without requiring a stepped peghead hole, taking pressure off the post and mounting screw.
Featuring permanent Schaller special grease lubrication, every sealed machine is entirely maintenance-free. The dual-pin design matches the classic housing dimensions with 0.4 in (10 mm) pin spacing for seamless upgrades and reliable instrument stability.
