Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an improved 1:18 gear ratio. CNC-machined to exacting tolerances, its self-locking drive ensures consistent and delicate adjustment without unwanted backlash.
Featuring high-grade brass string posts precision-fitted to the sealed housing, this tuner delivers wear-free performance. Each unit is permanently lubricated with Schaller special grease for completely maintenance-free operation across its entire lifespan.
The innovative stepped M6 flanged washer centers the string post securely over the threaded bushing, eliminating the need for a stepped peghead hole. It matches the original M6 footprint perfectly for direct drop-in replacement on compatible instruments.
