Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for precision, tuning stability, and reliability. Featuring an advanced 1:18 gear ratio, it ensures smooth, fine-tuned adjustments for flawless pitch accuracy. Each component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Equipped with high-grade brass string posts engineered for maximum wear resistance, the M6 135 guarantees long-lasting mechanical integrity. The innovative stepped flanged washer centers the string post securely through the banjo bolt, eliminating tilt and removing mechanical pressure from both the post and rear mounting screws without requiring stepped headstock drilling.
Designed with standard mounting dimensions identical to its predecessor, the M6 135 enables drop-in replacement on compatible guitars without permanent headstock modifications. Whether configured for slotted or solid headstocks, standard or locking formats, it provides tour-grade dependability and refined craftsmanship.
