Kuhnl & Hoyer Orchestra Signature Bass Trombone with Open-Flow Rotors and Screw Bell Flare


Item Details

The K&H Orchestra Signature bass trombone is a premier instrument custom made in Markt Erlbach, Bavaria, Germany.  Most notable is that it's available in this handy travel size.

This is one of very few bass trombones featuring the Meinlschmidt Open-Flow rotary valves.  These rotors are remarkable, and when mated to a fine German instrument like the Kuhnl & Hoyer, it's captivating.

For those who travel, this trombone has a removable flare.  The sleek Bonna case looks like a viola case.  No one will bother you about it.

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, but not much.  Only a few players seek stacked valves anymore, so inline it is.

Extra attention is paid to ergonomics on these trombones.  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 more comfortably and a clever hand rest supports the back of the player's left hand.
