Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets high standards for closed tuning systems, delivering exceptional precision and smooth operation with its 1:18 gear ratio. Every component is CNC-machined to exact tolerances, paired with premium brass string posts that fit snugly into the housing to maximize tuning stability and resist wear over long-term use.
Equipped with an innovative stepped M6 flanged collar, this tuner eliminates the need for stepped headstock holes while reliably centering the string post via the hollow bolt. This design effectively removes tilting torque and relieves mechanical stress from both the post and the rear mounting pins.
Permanently lubricated with specialized grease for maintenance-free reliability, the M6 Pin utilizes a 10 mm pin spacing with an 8 mm center distance from pins to string post for secure mounting on compatible guitar headstocks.
