Buzzz Master by David O'Neill For Large Shank Tuba Made in USA By Warburton Brand new, unused (only opened for photos). I have used the trumpet version before and thought it would help with practice, but I accidentally bought the large shank tuba version. I've included a reference image with a Perantucci (normal shank) inserted. *Mouthpiece not included. The surface appears to be satin finish. *I have one more available, so please let me know if you'd like to purchase them together. Will be shipped via Yu-Packet Post Mini.
