Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single delivers an exceptional blend of classic vintage styling, precise tuning accuracy, and ultra-smooth operation. Designed with open-gear architecture and precision worm gearing, this tuner brings refined mechanical elegance to acoustic, electric, and archtop guitars.
Featuring a 1:18 gear ratio, the mechanism provides outstanding precision and long-lasting durability. The open design avoids synthetic polymer coatings, allowing for direct resonance transfer throughout the instrument's headstock while ensuring wear-free contact surfaces and reliable tuning stability.
Engineered to standard instrument dimensions for straightforward replacement and installation, it features permanently locked and sealed screw connections along with countersunk screw holes for solid mounting and optimal acoustic coupling.
