Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and tuning stability. Engineered with a refined 1:18 gear ratio, it provides smooth, velvety action and accurate tuning performance. Every component is CNC-machined and permanently lubricated with Schaller special grease for maintenance-free operation.
Featuring high-grade brass posts fitted seamlessly into the housing, this tuner maximizes wear resistance and string vibration transfer. The innovative stepped M6 flanged washer centers the string post reliably via the threaded bushing, eliminating tilting torque and removing unnecessary strain from both the post and rear mounting screws.
Designed for straightforward installation and versatile configuration, the M6 Pin utilizes dual locating pins with a 0.39 in (10 mm) center-to-center spacing. Whether set up with standard posts or advanced locking mechanisms, it delivers exceptional reliability and enduring tuning accuracy for modern players.
