Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine continues the legacy of closed machine heads with refined engineering and exceptional stability. Designed with a 1:18 gear ratio, it delivers ultra-precise, velvet-smooth tuning performance for discerning players.
Precision CNC-machined components and high-grade brass string posts provide wear-free longevity and exceptional pitch stability. All closed housings feature permanent self-lubrication using Schaller specialty grease, making them completely maintenance-free.
The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock hole, eliminating tilting torque. Retaining identical mounting dimensions to its historic predecessor, the M6 135 allows direct, modification-free retrofitting.
