Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. All components are CNC-machined to exact tolerances, high-grade finished, and permanently lubricated with Schaller special grease for maintenance-free operation and smooth performance.
Featuring high-quality brass string posts precisely fitted into the housing, this machine head ensures maximum tuning stability and wear resistance. An innovative stepped M6 flanged washer centers the post reliably via the threaded bushing, eliminating tilting torque without requiring a counterbore in the headstock.
Designed with a precise 10 mm pin spacing, the M6 Pin incorporates a self-locking drive for fine, stable adjustments across diverse stringed instrument setups.
