Hello everybody,
what would you think of playing a mouthpiece Warburtron 3MD with a tail 7* ? Would you think it would be balanced ? For instance to play as second trumpet or whatever.

I play on a Warburton. It is a 3sv with a BKT backbore. You have to play the mouthpiece and see how it sounds in the setting that you are in. You may have to switch but then again it may work. Try it and see what happens
