Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune represents the ultimate combination of elegant vintage styling, precise tuning behavior, and velvet-smooth performance. Built as an open-gear tuner with an ultra-precise worm gear mechanism, it delivers exceptional tonal resonance without the need for synthetic coatings.
Featuring an 1:18 gear ratio, this tuning machine provides uncompromising accuracy and long-term durability. The precision contact surfaces operate without polymer layers to ensure seamless stick-slip performance and zero wear or aging over years of active playing.
Engineered to standard instrument dimensions for trouble-free installation and replacement, each unit includes permanently locked and sealed screw joints alongside countersunk mounting holes that maximize sound transmission into the headstock.
