Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry benchmark for precision, tuning stability, and refined craftsmanship. Featuring a 1:18 gear ratio, this closed-type tuning machine ensures a smooth, highly responsive, and reliable tuning experience. All structural components are CNC-machined with high accuracy and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Equipped with solid brass string posts that fit precisely into the housing, the M6 135 prevents premature wear while maximizing pitch retention. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped peghead drilling, effectively eliminating tilt momentum and reducing mechanical stress on both the shaft and rear mounting screw.
Designed with standard dimensions identical to previous iterations, the M6 135 allows for seamless, direct-replacement installation on compatible instruments. Its robust engineering makes it an exceptional upgrade for maintaining consistent string tension and optimal performance.
