The Schaller GrandTune 3+3 machine heads combine traditional open-gear styling with precise, consistent tuning performance. Designed as a classic tuning machine, the GrandTune focuses on mechanical accuracy, smooth operation, and long-term reliability.
A 1:18 gear ratio provides fine tuning control with a stable, fluid feel. The mechanism is manufactured without synthetic coatings, allowing direct metal contact at critical interfaces. This construction supports resonance transfer while avoiding wear associated with ageing polymer layers. Precision-machined contact surfaces ensure smooth operation and consistent performance over extended use.
The tuning mechanism uses permanently secured, sealed screw connections to maintain alignment and minimise maintenance requirements. Dimensions are based on common production guitar specifications, allowing straightforward installation or replacement on most series instruments.
Special features
Precision-machined contact surfaces without polymer coatings provide consistent lubricity without wear or degradation over time.
Sealed and permanently secured screw connections ensure stable, maintenance-free operation.
Standardised dimensions support compatibility with common production headstocks.
