Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 sets the benchmark for closed guitar tuning machines with an advanced 1:18 gear ratio, delivering precise, smooth tuning and exceptional pitch stability. High-precision CNC-machined components and self-locking drive mechanics ensure durable and sensitive adjustments for any performance demand.
Crafted with premium brass string posts and permanently lubricated with Schaller special grease, these tuners are completely maintenance-free. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped peghead drilling, effectively eliminating tilt torque and protecting mounting hardware.
Engineered to match the exact mounting dimensions of previous M6 models, the M6 90 allows for seamless direct replacement and retrofitting on electric and acoustic guitars.
