The new K10 F/Bb-Double horn is the newest innovation for the orchestra: It was designed in close cooperation with Markus Wittgens. A well-orchestrated middle range, a great low register and an unknown ease in the higher area is obtained with a light rotary valve set, a full flow switch valve and an individually adjustable mouthpiece receiver. A pleasant well-balanced set-up, supported by both a fully adjustable fingerhook and thumblever plus flipper guarantees perfect ergonomics. Every K10 has a detachable bell and is delivered in an original MB case.
