Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth operation with an improved 1:18 gear ratio. As an evolution of the legendary closed-housing tuner originally introduced in 1966, this model pairs time-tested reliability with modern mechanical innovations.
Precision CNC-machined components and solid brass string posts provide exceptional tuning stability, smooth action, and zero wear. The internal self-locking drive and lifetime lubrication with Schaller special grease ensure completely maintenance-free performance.
Equipped with an innovative stepped M6 flanged washer, this tuner aligns reliably without requiring stepped headstock drilling. This design eliminates tilting torque and effectively absorbs stress on both the string post and rear mounting screw.
