Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines refined vintage styling with precise, velvety-smooth tuning performance. Designed as a perfected open-gear tuning machine, it features an exposed gear and worm drive engineered for enduring reliability and classic aesthetics.
A precise 1:18 gear ratio delivers fine tuning accuracy and outstanding longevity. Built completely free of synthetic polymer coatings, the ultra-precise contact surfaces optimize acoustic coupling, allowing the instrument headstock to resonate naturally without unwanted friction or premature wear.
Crafted to standard production dimensions, these tuners feature permanently locked, sealed screw fittings and countersunk mounting holes to ensure effortless installation, a firm fit, and optimal acoustic transfer.
