Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and smooth operation with an improved 1:18 gear ratio. Designed with CNC-machined parts and high-grade brass string posts, these sealed tuners provide maximum tuning stability and long-lasting wear resistance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by eliminating the need for a stepped peghead bore while perfectly centering the string post. The system effectively eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screws.
Every enclosed tuner is permanently lubricated with Schaller special grease for completely maintenance-free performance. Featuring a secure dual-pin design with 0.39 in center-to-center pin spacing, these machine heads ensure reliable and precise guitar tuning.
