Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines refined vintage aesthetics with precise tuning response and ultra-smooth operation. Designed as an open-gear tuner with an 18:1 gear ratio, it ensures exceptional tuning accuracy and lasting durability without relying on synthetic coatings that deaden resonance.
Crafted with ultra-precise contact surfaces to eliminate stick-slip friction, this tuner features permanently locked and sealed screw connections for completely wear-free performance. Standard dimensions match common production instruments for seamless direct replacement and solid headstock resonance.
Recessed screw holes provide firm seating and optimal vibrational transfer to the wood. Deluxe string roller variants integrate end ball bearings to prevent binding, friction, and clicking noises within classical guitar peghead bores.
