Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. CNC-machined components with premium surface finishing and a self-locking drive ensure precise, consistent, and wear-free string adjustments.
Crafted with high-grade brass string posts and permanently lubricated with Schaller special grease, these sealed tuners provide maintenance-free performance and superior tuning stability for solid and slotted headstocks.
The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock drilling, effectively eliminating tilting torque and reducing mechanical stress.
