Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine features a refined 1:18 gear ratio that delivers precise, velvety-smooth tuning stability and control. Building upon the legendary closed tuning machine standard established in 1966, this model incorporates CNC-machined components with a self-locking drive and surface finishing for sensitive and consistent operation.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine provides maximum tuning stability and wear-free performance. The specialized step-flanged washer reliably centers the post without requiring a stepped peghead bore, eliminating tilting forces and reducing load on the string post and rear mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free reliability, the M6 180 is engineered to drop into place without peghead modifications. High-precision manufacturing ensures smooth gear engagement, making it an exceptional replacement or upgrade for modern and vintage instruments alike.
