K· housing is made in a single piece through precision mechanical machining on 5-axis machines. In fact, the piece is not made by moulding or casting, as tuners manufacturers usually do. The components thus obtained are solid, compact and perfectly fitting on the guitar headstock. The use of lightweight and high-performance materials, such as aluminium and titanium, guarantees a reduced weight compared to normal commercial products. The resulting advantages are an excellent weight balance of the instrument, and an even and balanced distribution of the sound throughout the guitar neck.
