Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-gear tuners, featuring an advanced 1:18 gear ratio that ensures velvet-smooth, pinpoint tuning accuracy. Every component is CNC-machined to exact tolerances and factory-lubricated with Schaller special grease for completely maintenance-free, self-locking operation.
Equipped with high-grade brass string posts engineered for maximum tuning stability, this model introduces the innovative stepped M6 flanged washer. The 0.39 in diameter stepped base reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing strain on both the post and the rear mounting screw.
Designed with identical installation dimensions to its classic predecessor, the M6 135 serves as a direct, drop-in replacement that requires no modifications to your guitar headstock. It delivers rock-solid performance and long-lasting durability for modern and vintage instruments alike.
