Please remember to specify your desired Rim SizeNOTE:
You may use the Warburton trumpet/cornet backbore you aleady own, or order the SILVER PLATED A.T.V. shank here
or the GOLD PLATED version hereWhat size A.T.V. do you need ?
If you already play a Warburton mouthpiece, all the A.T.V. rim diameters are the same as our regular mouthpieces. For example, if you play a Warburton 4SV you would want the size 4 A.T.V.
If you play another manufacturer's mouthpiece, our trumpet mouthpiece comparison chart
may be able to help you find the Warburton size that matches your mouthpiece. For example, if you play a Schilke 15 you should order the size 3 A.T.V.
