Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune offers a refined blend of vintage aesthetic, pinpoint tuning accuracy, and velvet-smooth operation. Designed with an open gear and worm drive architecture, it provides an advanced tuning platform built for classical, acoustic, and electric guitars.
Featuring a precise 1:18 gear ratio, this tuning machine delivers exceptional longevity and tuning stability. The omission of synthetic coatings creates an uninhibited, perfectly resonating unit that maximizes tone transfer and maintains enduring mechanical performance.
Crafted with ultra-precise contact surfaces and permanently sealed fittings, each machine ensures wear-free and maintenance-free functionality. Its standardized dimensions allow for direct fitment and effortless replacement on production instruments.
