Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets the standard for closed guitar tuning machines with an advanced 1:18 gear ratio that delivers precise, velvety-smooth tuning and exceptional pitch stability. High-precision CNC-machined components with refined surface finishes and self-locking drive mechanisms ensure uniform, delicate adjustments across every string.
Equipped with high-grade brass posts precisely fitted into the housing, these tuners provide maximum wear resistance. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing pressure on both the post and rear mounting screw.
Featuring permanent lubrication with specialized grease, each closed tuner is completely maintenance-free. With identical installation dimensions to its predecessor, the M6 135 allows direct drop-in replacement and straightforward installation on standard guitar headstocks.
