Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability with its refined 1:18 gear ratio. All components are high-precision CNC-machined and surface-finished, featuring a self-locking drive mechanism that ensures smooth, sensitive, and reliable adjustments.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine provides maximum wear resistance and zero-maintenance operation thanks to Schaller special grease lubrication. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moments without requiring stepped headstock peg holes.
Designed as a modern evolution of the classic closed-back machine head, the M6 180 offers seamless drop-in replacement functionality with classic aesthetics. It provides enduring mechanical performance and tuning accuracy for discerning musicians and custom instrument builders.
