Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single Guitar Tuning Machine combines refined vintage aesthetics with precise tuning capability and smooth operation. Designed as an open-gear tuner with a threaded worm gear, it delivers an 18:1 gear ratio for high accuracy, stability, and enduring performance.
Constructed without synthetic coatings, the tuner ensures direct, natural resonance transfer to the instrument. Its ultra-precise contact surfaces provide optimal stick-slip action free from wear and degradation over extended use.
