Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for closed-type tuners, offering an advanced 1:18 gear ratio for ultra-precise and smooth tuning action. Designed with precision CNC-machined components, it features a self-locking drive mechanism that ensures velvety response and unmatched tuning stability.
Engineered for maximum durability, all string posts are precision-machined from premium brass and fitted securely into the housing to eliminate wear. The innovative stepped M6 flanged washer reliably centers the string post without requiring stepped peghead drilling, absorbing lateral forces and safeguarding mounting screws.
Each sealed tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation across its entire lifespan. Dual rear locating pins ensure rock-solid installation with standardized 0.4 in (10 mm) pin-to-pin spacing and 0.3 in (8 mm) spacing from pins to string post center.
