The King Duo-Gravis Silver Sonic bass trombones have attracted a cult following with good reason: They have a sound that is unmatched by any other model.
This instrument is in very good condition considering its age. The expected lacquer wear and some previous dent work is can be seen in the bell but none of that affects the performance of this great horn. The "D" slide was custom built by our shop. The sterling silver bell is 9.5".
