Warburton Trumpet A.T.V. SHANK Only
 
Note that the low-cost A.T.V. shank does not have (or need) a hole bored through it. It's exactly the
same as our regular backbores, except that we reduced the cost by not finishing the interior bore.
When using your A.T.V. there is no sound or air moving through the trumpet which means you
may use a shank with or without the bored hole - they both work the same for A.T.V. use.
 
NOTE: CANNOT be used with a regular top for playing - ONLY WORKS WITH THE A.T.V.
