Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 represents the modern evolution of the legendary enclosed guitar tuning machine, engineered to deliver unparalleled tuning accuracy and velvet-smooth operation. Featuring a refined 1:18 gear ratio and high-precision CNC-machined components, it provides exceptionally sensitive, stable, and wear-free adjustments.
Built with premium solid brass string posts precisely fitted into the housing, this tuning machine incorporates the innovative stepped M6 flanged washer. This stepped collar centers the string post securely through the headstock hole, eliminating tipping torque and relieving strain on both the post and rear mounting screws without requiring specialized step drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free longevity, the M6 180 offers drop-in compatibility for seamless replacement of earlier models. Its robust self-locking drive mechanism ensures maximum tuning stability under all playing conditions.
