Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 tuning machine features an advanced 1:18 gear ratio that delivers precise, velvety-smooth tuning response and exceptional stability. CNC-machined components with premium surface finishing guarantee even, sensitive adjustment, while precision-fitted brass string posts eliminate mechanical play and prevent premature wear.
Equipped with Schaller's innovative stepped flanged washer, this machine head mounts securely and self-centers the string post through the banjonut, eliminating tilting moments and relieving stress from both the post and rear mounting screw. The sealed housing incorporates permanent lubrication with proprietary Schaller grease, rendering the internal mechanism completely maintenance-free.
Retaining identical mounting dimensions to its legendary predecessor, the M6 90 allows seamless drop-in replacement on standard headstocks without structural modifications. Its self-locking drive and durable architecture make it a reliable professional upgrade for players seeking peak tuning accuracy and rock-solid performance.
