"Conn 62HG Pro Bass Trombone with Greenhoe Valves 62HG
The open-wrap Conn 62HG provides a custom bass trombone sound for an affordable price. Featuring an independent valve system designed by professional trombonist Gary Greenhoe, the 62HG allows the travel of the sound path to be very short through the valves to minimize distortion.
