Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning stability and silky-smooth operation with its refined 1:18 gear ratio. Designed with CNC-machined precision components and premium brass string posts, it ensures long-lasting durability and zero-play performance.
Equipped with Schaller's innovative stepped flanged washer, this machine head centers the string post securely without requiring stepped peghead drilling. This design eliminates tilting torque and protects both the internal mechanism and rear mounting screw from unnecessary strain.
Permanently lubricated with Schaller special grease for maintenance-free reliability, the M6 135 shares identical installation dimensions with its classic predecessor, allowing for seamless drop-in replacement on compatible headstocks.
