Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets the standard for closed tuners with a refined 1:18 gear ratio for smooth, precise, and stable tuning. Each component is CNC-machined and finished to high precision, featuring a self-locking drive and premium brass string posts that ensure zero-play performance and long service life.
Featuring an innovative stepped flanged washer with a 0.4 in (10 mm) base diameter, this design accurately centers the string post through the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical strain on both the string post and rear fixing pins.
Equipped with dual rear mounting pins at a 0.4 in (10 mm) center-to-center spacing, these tuners are lubricated with Schaller special grease for completely maintenance-free operation. The package includes mounting banjo bolts, flanged washers, and M2.2 x 0.4 in (9.5 mm) installation screws.
