Kanstul 1670 Model "George Roberts" Single Valve Bass Trombone. Has 9" Bronze one piece bell with gold brass tuning in handslide T.I.S. Very similar handslide to the legendary Conn 62H model. If ever there was an ideal Bass for a tenor doubler playing in a big band, or just someone who wants to learn to play bass but doesn't want all of the weight on their left shoulder/arm, THIS IS THE IDEAL INSTRUMENT. Single owner horn was purchased directly from Kanstul, made by Zig himself. No flaws or defects. Has had our full shop service, chemical bath and has been adjusted for maximum playabiltiy. Comes with Super Excellent condition and also super rare Black Leather Reunion Blues Case. Three leadpipes also included. Not many of these available, not many of them made period. When Kanstul was still making this model, dealers were selling them new for over $3600.
