Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio that delivers exceptional precision, velvety smooth action, and outstanding tuning stability. Every component is CNC-machined and finished to tight tolerances, with high-grade brass string posts engineered directly into the housing to ensure frictionless, long-lasting performance and zero play.
Installation is streamlined and secure thanks to the innovative stepped M6 flanged collar with a 0.39 in (10 mm) base. This unique design eliminates the need for stepped headstock drilling by self-centering the string post through the banjo bolt, effectively absorbing string tension and preventing tipping torque on both the post and rear mounting pins.
Engineered for maintenance-free operation, all enclosed housings are permanently lubricated with proprietary Schaller special grease. Designed as a direct two-pin replacement with standard 0.39 in (10 mm) pin spacing and a 0.31 in (8 mm) post-to-pin offset, this versatile system offers robust reliability and professional-grade performance for discerning players.
