Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers renowned tuning stability and mechanical precision. Built with a refined 1:18 gear ratio, it provides smooth, sensitive, and accurate tuning control across all strings. High-precision CNC-machined components and self-locking drive mechanics ensure reliable performance and lasting durability.
Crafted with premium brass string posts fitted precisely into the housing, these enclosed machine heads eliminate play and resist wear over years of use. An innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moments and removing the need for a stepped peghead bore.
Permanently lubricated with specialized Schaller grease, each tuning machine requires zero ongoing maintenance. The standardized two-pin configuration allows direct replacement on compatible headstocks while maintaining optimal string tension and alignment.
