Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers exceptional tuning precision and stability with an improved 1:18 gear ratio. CNC-machined components with a self-locking drive mechanism ensure velvet-smooth operation, fine adjustment, and lasting performance without slippage.
Crafted with premium high-grade brass posts fitted seamlessly into the housing, this enclosed tuner features permanent internal lubrication with Schaller special grease for completely maintenance-free operation. The stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock bore, effectively removing lateral pressure from both the post and mounting screws.
Designed for versatile guitar setups, the M6 Pin incorporates precise two-pin mounting for steady alignment and rock-solid vibration transfer. Every component is engineered to eliminate play and maximize long-term tuning reliability across demanding playing conditions.
