Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines refined vintage styling with pinpoint tuning precision and ultra-smooth operation. Designed with an open-gear architecture and precise worm drive, it provides exceptional resonance and tone transfer across your guitar.
Featuring an 18:1 gear ratio, this tuning machine delivers exact intonation and lasting stability. The design omits synthetic polymer coatings, relying instead on precision-machined contact surfaces to create optimal stick-slip movement without wear or degradation over time.
Built with permanently locked, sealed joints for maintenance-free performance, it uses standard serial instrument dimensions for straightforward installation. Countersunk screw holes ensure secure fastening and pure acoustic sound coupling.
