Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 tuning machine sets a benchmark for closed guitar tuners, combining legendary heritage with refined modern engineering. Featuring an advanced 1:18 gear ratio, it provides velvety smooth action, unmatched precision, and effortless tuning stability for demanding players.
Every internal component is high-precision CNC-machined and surface-finished, utilizing high-grade brass string posts engineered seamlessly into the housing. A self-locking drive and permanent lubrication with Schaller special grease ensure maintenance-free performance, zero wear, and lasting durability.
Installation is straightforward thanks to identical footprint dimensions matching predecessor models. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, preventing tilt and eliminating the need for a stepped peghead bore.
