Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, offering smooth operation and exceptional tuning stability. Engineered with a refined 1:18 gear ratio, it provides unmatched precision for fine, sensitive adjustments. All components are CNC-machined to exact tolerances, premium finished, and permanently lubricated with Schaller special grease for completely maintenance-free performance.
Featuring high-grade brass string posts precisely fitted into the housing, this tuning machine guarantees maximum wear resistance and pitch stability. The innovative stepped M6 flanged washer ensures straightforward installation and lasting centering of the post, eliminating tilting torque and reducing mechanical stress on both the string post and rear mounting screws without requiring stepped drilling in the headstock.
Equipped with a rear-pin mounting system featuring a 0.39 in pin-to-pin spacing and a 0.31 in pin-to-post distance, this tuner offers a secure fit and dependable lock. The integrated locking mechanism delivers swift string changes and superior stability under demanding playing conditions.
