Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines classic open-gear vintage aesthetics with ultra-precise tuning performance and velvety smooth action. Engineered without synthetic coatings, it delivers high resonance and wear-free interaction designed to match the lifespan of fine instruments.
Featuring a 1:18 gear ratio, this tuning machine provides exceptional precision and tuning stability. Ultra-precise contact surfaces create optimal stick-slip action without polymer layers, while permanently locked and sealed screw connections ensure maintenance-free reliability.
Designed to fit standard instrument dimensions, it allows straightforward installation and replacement on solid or slotted headstocks. Recessed mounting screw holes promote firm attachment and optimal acoustic transfer to the guitar.
