Schaller GrandTune Guitar Tuning Machine

The Schaller GrandTune combines refined vintage styling with precise tuning response and ultra-smooth performance. Built as an open-gear tuning machine with precision worm gears, it delivers uncompromised resonance and stability across a wide variety of instruments.
Equipped with a 1:18 gear ratio, the GrandTune ensures pinpoint accuracy and extended operational life. The design omits synthetic polymer coatings in favor of ultra-precise contact surfaces, producing wear-free stick-slip performance without tonal damping.
Engineered to standard instrument dimensions for straightforward installation or replacement, each tuner features permanently locked, sealed screw joints and countersunk screw holes to ensure firm anchoring and optimal sound transmission.
