Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets a high benchmark in closed guitar tuning machines, equipped with an advanced 1:18 gear ratio that delivers exceptional tuning precision and ultra-smooth operation. CNC-machined components with premium surface finishes work alongside a self-locking drive to ensure dependable tuning stability and sensitive adjustment.
Engineered with precision-fitted brass string posts, each unit guarantees zero wear and maximum structural integrity over long-term use. The innovative stepped M6 flanged washer centers the string post securely via the hollow screw, eliminating tipping torque and removing the requirement for stepped peghead drilling.
Permanently lubricated with specialized Schaller grease for maintenance-free reliability, the M6 135 retains the identical mounting dimensions of its historic predecessor for direct, seamless replacement on compatible headstocks.
