Buzzz Master by David O'Neill For Large Shank Tuba Made in USA By Warburton Brand new, unused (only opened for photos). This is a buzzing practice tool made by Warburton. I've used the trumpet version before and thought it would help with practice, so I bought this, 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 has a satin finish, and the retail price seems to be around 10,000 yen. *I have two more, so please let me know if you'd like to buy them in bulk. Shipping is planned via Yu-packet Post mini.
