Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin series sets the standard for closed guitar tuning machines with an advanced 1:18 gear ratio that delivers precise, velvety-smooth tuning comfort and exceptional stability. Each component is CNC-machined to exact tolerances and surface-finished, featuring a self-locking drive and precision-fitted brass string posts that eliminate wear and maintain rock-solid pitch.
An innovative stepped M6 flanged washer ensures straightforward installation and durable centering of the post over the threaded bush, eliminating tilting moments and relieving stress from both the post and rear mounting points without requiring stepped headstock holes.
Equipped with permanent Schaller special grease lubrication, these sealed tuning machines offer completely maintenance-free performance. Designed with a dual-pin mounting configuration and an 8 mm spacing from pins to string post center, they provide an exact replacement fit for standard M6 pin footprints.
