Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. CNC-machined from premium materials, its brass string posts and self-locking drive ensure velvety smooth operation and reliable tuning stability.
Equipped with the innovative stepped M6 flanged washer, this tuner centers the string post securely without requiring stepped headstock drilling. This smart design eliminates tilting moments and relieves mechanical stress from both the post and the rear mounting screw.
Permanently lubricated with Schaller special grease for entirely maintenance-free longevity, the M6 135 retains the identical mounting dimensions of its classic predecessor for effortless drop-in replacement on electric and acoustic guitars.
