Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-gear tuners, featuring an advanced 1:18 gear ratio that delivers exceptional precision and smooth, velvet-like tuning feel. Every component is CNC-machined to exacting tolerances and treated with a durable surface finish, while high-grade brass string posts fit precisely into the housing to guarantee maximum wear resistance and tuning stability.
An innovative stepped M6 flanged washer streamlines installation and reliably centers the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces direct pressure on both the string axis and rear mounting pins. Permanent lubrication with Schaller specialized grease ensures completely maintenance-free operation over a lifetime of use.
Equipped with a rear dual-pin alignment system featuring a 0.39-inch (10 mm) pin spacing, this tuning machine provides rock-solid positioning on compatible headstocks. Premium self-locking internal mechanics deliver consistent, sensitive, and reliable string tension control for both stage and studio instruments.
