Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine features a refined 1:18 gear ratio that delivers exceptional tuning accuracy, smooth operation, and superior pitch stability. Precision CNC-machined components and a self-locking drive mechanism ensure consistent, sensitive, and dependable adjustments under all playing conditions.
Crafted with premium high-grade brass string posts engineered precisely into the housing, these tuners provide maximum wear resistance and long-lasting performance. The innovative stepped M6 flanged washer reliably centers the string post and eliminates tilting torque without requiring stepped drilling in the headstock.
Each closed tuner is permanently lubricated with Schaller special grease for completely maintenance-free functionality. Designed with a 0.39 in (10 mm) pin-to-pin spacing and an 0.31 in (8 mm) distance between pins and post center, this model provides seamless mounting for compatible guitar headstocks.
