Schaller GrandTune Single Guitar Tuning Machine
$30.00Price
The Schaller GrandTune Single Guitar Tuning Machine combines vintage styling with precision tuning and velvet-smooth performance. Built as an open-gear tuning mechanism with a precision-machined worm gear, it delivers an exact 1:18 gear ratio for fine-tuning stability and longevity.
Crafted without synthetic coatings, the tuning machine features ultra-precise contact surfaces that produce seamless stick-slip behavior without wear or aging. Permanently locked, sealed screw joints ensure maintenance-free operation across years of play.
Standard production dimensions and countersunk screw holes allow for straightforward installation, retrofitting, and optimal acoustic resonance on solid or slotted headstocks.
