Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 tuning machine features a refined 1:18 gear ratio that provides velvety smooth operation and precise, dependable tuning. Manufactured to high tolerances with precision CNC machining, each component is surface-finished and incorporates a self-locking drive to guarantee consistent, fine-tuned pitch adjustment and exceptional stability.
Crafted with premium brass string posts fitted accurately into the housing, the M6 90 ensures maximum durability, wear-free performance, and reliable centering. All enclosed tuners come permanently lubricated with Schaller special grease, rendering them completely maintenance-free throughout their lifespan.
Equipped with an innovative stepped flanged washer, this machine head centers the post securely through the threaded bushing without requiring stepped peghead drilling. It shares identical mounting dimensions with its predecessor model, allowing seamless drop-in replacement on electric and acoustic guitars without instrument modifications.
