Conn 4B Bass Trumpet, Vintage Elkhart Indiana. Not many 4B's available used. In fact we think this is the best one on the internet today. This one has had full shop service, chemical bath, pads, felts, valves good, no leaks, compression fine, thoroughly play tested personally. A Bach 7C small shank trombone mouthpiece was a great fit and played fantastic. It made me feel like Lee Morgan or Freddie Hubbard when I played it. But, we know that there aren't many Jazz players using instruments like this. The original use for the 4B was most likely symphonic, but a lot of marching bands had them as well. Regardless, it's very easy to play, and sounds beautiful when played properly. Original case, no mouthpiece. IN-Stock
