Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed with high-precision CNC-machined components and surface finishing, it ensures even, sensitive, and stable tuning performance.
Equipped with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear resistance. Closed housings are permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring the innovative stepped M6 flanged washer, it centers the string post reliably through the banjonut and prevents tilting without requiring stepped peghead drilling. It matches the exact installation dimensions of its predecessor for direct replacement.
