Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning precision and stability with an upgraded 1:18 gear ratio. Designed with high-precision CNC-machined components and a self-locking drive, it provides smooth, delicate, and reliable operation for electric and acoustic guitars.
Constructed with premium brass string posts precisely fitted into the housing, these tuners ensure maximum durability and wear-free performance. Closed housings are permanently lubricated with Schaller special grease, making the internal mechanisms completely maintenance-free over their lifespan.
The innovative stepped M6 flanged washer reliably centers the string post through the banjo bolt, eliminating the need for a stepped peghead hole. This system distributes pressure evenly and prevents tilting torque on the post, perfectly matching original M6 installation dimensions for seamless direct-replacement retrofits.
