Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Designed to match the exact mounting dimensions of its predecessor, it allows seamless replacement on compatible headstocks without modification.
Every component is CNC-machined to precise tolerances and surface-finished for smooth, velvet-like operation. High-grade brass posts ensure maximum wear resistance, while a self-locking drive and internal permanent lubrication provide maintenance-free reliability.
Featuring the innovative stepped M6 flanged washer, this tuner securely centers the string post without requiring stepped headstock drilling. This design eliminates tipping forces and relieves pressure from both the post and mounting screws.
