Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines classic vintage styling with precise tuning performance and velvety smooth operation. Designed with open-gear architecture and precision worm gearing, it delivers an optimal blend of acoustic resonance and mechanical reliability.
Featuring an ultra-precise 1:18 gear ratio, this tuning machine provides exceptional tuning accuracy and longevity. The absence of synthetic coatings ensures perfect resonance transfer across your instrument, while permanently locked and sealed screw connections guarantee zero-wear, maintenance-free operation.
Crafted to accommodate standard production guitar dimensions for easy retrofitting and installation, the GrandTune includes countersunk screw holes for solid anchoring and enhanced sound transmission.
