Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding tuning accuracy and smooth operation with an advanced 1:18 gear ratio. All components are CNC-machined to precise tolerances and surface-finished, featuring a self-locking drive mechanism that guarantees consistent, sensitive, and stable tuning.
Constructed with durable brass string posts fitted accurately into the housing, this tuning machine provides maximum tuning stability and wear-free performance. The innovative stepped M6 flanged washer ensures seamless installation and maintains solid, permanent axis centering over the banjo bolt without requiring a stepped peghead bore.
Featuring the exact installation dimensions of its predecessor, the M6 135 enables straightforward drop-in replacement without headstock modifications. All enclosed machine heads come permanently lubricated with specialized grease for completely maintenance-free longevity.
