Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine offers precision and tuning stability, driven by an optimized 1:18 gear ratio for smooth and delicate adjustment. High-precision CNC-machined brass string posts fit tightly within the housing, ensuring reliable wear-free performance and dependable self-locking operation.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear fixing screws.
Equipped with permanent internal lubrication via specialized grease, each sealed unit delivers lifetime maintenance-free performance. Designed with precision 2-pin indexing, it provides stable anchoring and a secure fit across compatible solid headstock instruments.
