Yibuy Silver Trumpet Mouthpiece with Golden 4 Sizes Convertible 7c 5c 3c 1.5c

Q: Does this come with the mouthpieces and the mouthpiece heads?

Yes, you change the mouthpieces on this to different sizes.

Q: I got the 3c top stuck in the main mouthpiece part and they wont unscrew. Is there a trick to unscrew them, like heat it up or cool it down?

If the mouthpiece top is stuck in the silver tube, I found putting it in the trumpet and trying to turn it out, it sometiems gets stuck so don’t tighten so hard! Good luck

Q: Do they fit in a bundy trumpet

Yes. But a better made mouthpiece (Bach, etc) will help a new student focus on tone and endurance.

Q: What is the metal or are the metals used?

The mouth pieces are polished brass. The stem that goes into the instrument is chrome plated brass. I used this kit to put the mouth piece on a shofar so that I could get a better sound. Works great. The kit comes with four sizes of the mouth piece. Try all four to get the best sound.
