Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single represents the ultimate combination of vintage styling, precision tuning, and velvet-smooth operation. Designed as a perfected open-gear tuning machine, it features an open gear with worm drive construction engineered for flawless acoustic and electric performance.
A precise 1:18 gear ratio delivers fine-tuning accuracy and long-term durability. By foregoing synthetic polymer coatings on its friction surfaces, the tuner forms a perfectly resonant bond with the instrument headstock, maximizing tone transfer and preventing wear or aging over extended playing life.
Engineered to standard instrument dimensions for trouble-free installation and replacement, each tuner incorporates permanently locked, sealed screw joints and countersunk screw holes that ensure rock-solid stability and zero maintenance.
