I can remember as a child my father had a dresser drawer full of many different makes and models of mouthpieces. Although for as long as I have known what a mouthpiece is, he has played the same 1.
I have never spent too much time or money when it comes most to trumpet equipment except for mutes.
Since the very beginning of my love affair with the trumpet I have loved the sound of the muted horn. Nothing better than the sound of Kenny Dorham or Fats Navarro wailin' through a cup mute. Louis swingin' hard in a plastic straight. Cootie growling, making the horn speak with a plunger. Of course, the cool sound of Miles in a Harmon.
Mutes are by far the fastest, most economical and fun way to change your sound.
I always take 4 mutes with me to all of my TUBA JAM and "jazz" gigs.
