Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering designed to maintain optimal tuning stability. Featuring an advanced 1:18 gear ratio, this sealed tuner delivers smooth and accurate action for electric and acoustic guitars. Each component is CNC-machined to exact tolerances, ensuring consistent and dependable performance across demanding playing environments.
Crafted with premium high-grade brass string posts fitted directly into the durable housing, this tuning machine provides maximum wear resistance. The specialized step flanged washer centers the string post securely through the headstock without the need for stepped drilling. This design eliminates tilting forces, distributing pressure away from both the string post and rear mounting screw.
Permanently lubricated with specialized grease, the closed housing ensures long-lasting, maintenance-free operation. Identical mounting dimensions to previous M6 iterations allow for straightforward retrofitting without modifying your instrument. It represents a refined standard in high-end guitar hardware craftsmanship.
