Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, offering unmatched precision and tuning stability. Engineered with a refined 1:18 gear ratio, it ensures an ultra-smooth, velvet-like tuning response and fine-tuning accuracy. Precision CNC-machined components and high-grade brass string posts guarantee wear-free operation and lasting reliability.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt. This eliminates the need for a stepped peghead hole, directly absorbing side-load pressure and securing the post against tilt. Each closed mechanism is permanently lubricated with Schaller special grease for completely maintenance-free performance.
Designed to match the exact mounting dimensions of its predecessor model, the M6 135 allows direct replacement without any instrument modifications. Ideal for upgrades and custom configurations, it provides top-tier performance for solid and slotted headstocks alike.
