Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines stylish vintage open-gear design with precision tuning stability and velvety-smooth performance. Built with an open gear and worm drive architecture, this classic tuner eliminates synthetic polymer coatings to ensure natural, resonant acoustic transfer throughout the instrument.
Featuring an ultra-precise 1:18 gear ratio, the tuning machine provides outstanding accuracy, smooth engagement, and long-lasting reliability. Permanently locked, sealed, and covered screw connections deliver consistent wear-free performance that stands up to demanding playing conditions.
Engineered to standard instrument dimensions for effortless installation and replacement, the tuning machine features countersunk screw holes for solid mounting and optimal acoustic resonance.
