Guitar Machine Heads – GrandTune – Schaller – Acoustic Guitar – Chrome

With its cutting edge Velvet-Tec* technology the all new Schaller GrandTune is the ultimate combination of tasteful design and velvet-smooth feel and touch. Due to its revolutionary conception the GrandTune offers a precision and longevity second to none. 1:18 gear ratio supports precise and velvet- smooth tuning. Hyper- accurate gear joints and fittings without polymer coatings present stick-slip-performance and zero wear and slackening. GrandTune features permanently locked, sealed and covered screw joints for zero degradation and maintainance-free performance. They rather help avoiding a common problem with classical guitar tuners and the contact of the rollers inside the headstock. The string roller’s ball bearings effectively cure increased friction and resistance between shaft and wood often resulting in crackling and creaking noises whenever the tuners are turned.
