Schaller M6 Mini Guitar Tuning Machine
The Schaller M6 Mini guitar tuning machine delivers renowned tuning precision and stability in a compact, lightweight housing. Engineered with a refined 1:18 gear ratio, it provides smooth, delicate adjustments and superior tuning comfort for standard and smaller headstocks alike.
Crafted with premium high-precision brass string posts and permanently lubricated sealed gears, each tuner is completely maintenance-free and ensures wear-resistant performance. The self-locking drive maintains flawless tuning stability under demanding playing conditions.
Featuring the innovative stepped M6 flanged collar, this design self-centers the string post through the threaded bushing without requiring stepped headstock boreholes. This effectively eliminates tilting torque and relieves mechanical stress from both the post and mounting screws.
