King 6B Duo Gravis Bass Trombone from the early 1980's. This is a dependent valve set-up with updated split triggers, has great ergonomics and has been improved from original configuration. Tuning is Bb/F/D. Has 9.5" Gold Brass Bell and light weight nickel silver handslide with yellow brass endcrook. Handslide is very straight and without defects on the inner slide tubes. Valve section is very quick and quiet. This horn has been around and played on a bit. A few dings and minor flare creases removed. It still plays great, exactly as it should. Would be a great fit for anyone looking for a pro level bass trombone not ready to move into the 3-6K range. Would make a perfect first bass trombone for any level player. No service needs to improve playability. Has had full shop service. Would also make an excellent school owned Bass. These are built like tanks and made to last. In-stock for immediate delivery.
