Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and tuning stability, continuing the legacy of closed tuning mechanisms. Featuring an improved 1:18 gear ratio, it ensures smooth, accurate, and reliable tuning adjustments for electric and acoustic guitars.
Crafted with CNC-machined components and high-grade brass string posts, each unit guarantees long-term durability and wear resistance. The self-locking drive and permanently lubricated internal gears with Schaller special grease ensure maintenance-free performance over extended use.
Engineered with an innovative stepped flanged washer, this tuning machine centers the string post securely through the banjo bolt without requiring tiered headstock drilling. It shares identical mounting dimensions with its predecessor, allowing seamless replacement without guitar modifications.
