Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuning machines, featuring a precise 1:18 gear ratio for smooth, velvety tuning and exceptional accuracy. All components are high-precision CNC-machined and surface-treated, utilizing a self-locking drive mechanism to deliver consistent, sensitive, and stable tuning performance.
Constructed with premium brass string posts precisely fitted into the housing, this tuning machine guarantees maximum tuning stability and wear resistance. Each closed unit is permanently lubricated with Schaller special grease, rendering it completely maintenance-free over extended playing sessions.
Installation is streamlined via the stepped M6 collar washer with a 0.39 in (10 mm) diameter base, which eliminates the need for stepped headstock drilling and removes tilting torque from the string post. The design ensures reliable axis centering and long-lasting mechanical protection.
