Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine features a precise 1:18 gear ratio that delivers smooth and accurate tuning performance. Built with CNC-machined components and self-locking drive technology, it ensures high tuning stability and sensitive adjustment.
Equipped with high-grade brass string posts and factory permanent lubrication, this closed tuner provides wear-free, maintenance-free operation. The stepped M6 flanged washer centers the string post securely without requiring a stepped headstock bore.
Featuring a dual-pin mounting configuration with a 10 mm pin-to-pin spacing and an 8 mm distance to the post center, it offers direct replacement compatibility with original Schaller single-pin and two-pin housings.
