Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuning mechanisms, featuring a precise 1:18 gear ratio for smooth, accurate, and stable instrument tuning. All components are high-precision CNC-machined with premium surface finishes, utilizing a self-locking drive and premium brass string posts fitted seamlessly into the housing for maximum durability.
Equipped with an innovative stepped M6 flanged washer, this machine facilitates effortless mounting and ensures permanent solid centering of the post without the need for stepped headstock drilling. This design eliminates tilt moment and relieves operational strain on both the string post and rear fixing screws.
Permanently lubricated with specialized Schaller grease for completely maintenance-free operation, the M6 135 matches identical installation dimensions of previous legacy models for easy drop-in replacement across compatible headstocks.
