Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for precision and tuning stability, featuring a refined 1:18 gear ratio for smooth, accurate adjustments. Originally defining closed tuners in 1966, this updated edition incorporates modern CNC manufacturing for velvet-smooth operation.
Crafted with premium brass string posts precisely fitted into the housing, each unit delivers reliable wear resistance and superior stability. The innovative stepped M6 flanged washer ensures straightforward installation and rock-solid post centering without requiring a stepped headstock bore.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 135 features identical mounting dimensions to its predecessor for direct, modification-free retrofitting.
