Guitar Machine Heads GrandTune Classic Hauser

Schaller GrandTune Classic Hauser Machine Heads with Guide Bushings (10 mm)

The Schaller GrandTune Classic Hauser represents the ultimate combination of stylish vintage design, hyper-accurate tuning, and velvety smooth performance. The Classic Hauser model impresses with its simple elegance and unengraved baseplates, widely appreciated by connoisseurs of high-quality classical guitars.

With a 1:18 gear ratio, these open-gear tuners offer unsurpassed precision and durability. The avoidance of synthetic polymer coatings ensures a perfectly resonant unit with zero wear, slackening, or stick-slip issues. This specific version features 10 mm guide bushings. It can be equipped with optional "String Roller Deluxe" posts that feature state-of-the-art ball bearings. These bearings eliminate friction between the post and the headstock wood, allowing for entirely noiseless and frictionless tuning.
