Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for closed-gear tuners, offering refined engineering and unmatched precision. Built with a 1:18 gear ratio, it delivers velvety-smooth, highly sensitive tuning and reliable performance. High-precision CNC machining and high-grade brass string posts guarantee exceptional stability and wear resistance.
Featuring Schaller's innovative stepped flanged washer, the unit centers the string post securely through the threaded bushing without requiring stepped peghead drilling. This mechanism eliminates tilting torque while relieving mechanical stress from both the post and the rear mounting screw. Every unit is permanently lubricated with Schaller special grease for completely maintenance-free operation.
Sharing identical mounting dimensions with its classic predecessor, the M6 135 provides an effortless, drop-in replacement without requiring guitar modifications. It accommodates varied configurations, including standard and locking posts, to ensure dependable pitch retention across diverse playing demands.
