Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 sets the benchmark for enclosed guitar tuning machines, delivering uncompromised tuning accuracy and smooth operation. Engineered with a precision 1:18 gear ratio, this model ensures fine-tuned control and exceptional pitch stability for any performance requirement.
Crafted with premium CNC-machined components and solid brass posts, each tuner offers friction-free movement and maximum wear resistance. The enclosed design is permanently lubricated with Schaller special grease, guaranteeing completely maintenance-free longevity.
