Kuhnl & Hoyer Orchestra Signature Bass Trombone with Inline Rotors


Sold Out

Item Details

The K&H Orchestra Signature bass trombone is a premier instrument custom made in Markt Erlbach, Bavaria, Germany.  The modular system allows customization to your preferences.  This is one of very few bass trombones featuring the new Meinlschmidt Open-Flow rotary valves.  These rotors are remarkable, and when mated to a fine German instrument like the Kuhnl & Hoyer, it's captivating.

This model with inline rotors in F/Gb/D is the modern setup for the most agility in the low range by permitting independent use of either rotor.  A slightly more resistant response enhances the highs in the tone, giving more center.  The pedal tones may feel more resistant compared to the stacked rotor setup.

Extra attention is paid to ergonomics.  The hand slide features a curved brace and the bell section has an additional curved brace behind the first trigger paddle.  The second trigger paddle is curved to fit comfortable and an additional hand brace is available to support the back of the player's left hand.
