Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets the standard for enclosed tuners with an advanced 1:18 gear ratio for velvety smooth, highly precise tuning. Built from premium CNC-machined components with durable brass string posts, it ensures long-term wear resistance and outstanding tuning stability.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical strain on both the string post and rear mounting screws.
Featuring permanent internal lubrication with Schaller special grease, each enclosed unit is completely maintenance-free. Self-locking drive mechanics provide steady, delicate adjustments, making it a reliable upgrade for discerning guitarists.
