Conn 52J CC tuba

[Matt Walters]

To Ouch and Original Poster.
I built the original prototype for this tuba and used a mouthpiece receiver setup that let people use American, European and Large shank receivers. The Conn factory made some changes for the worse from what I sent them but they kept the receiver. Just find the mouthpiece that feels good to you and plays well. They came from the factory with a Conn Helleberg (120-S). I like and used a Geib cup mouthpiece when I built the King CC that became the Conn 5xJ series of tubas.

Ouch,
Because of some changes they did to what I gave them, the slots are very subtle. You may be over driving the tuba and lipping up to get the response and pitch centers. Relax and tune starting with the C in the staff. You should start feeling the more subtle and flatter slots the pros use. If this is what is happening, it is a very easy (cheap) thing for me to improve the response and slots of the tuba the next time you visit us at Dillon Music. Please call ahead. No, I can't just tell you by email how to do it.

Thank you so much! It's nice having advice from someone who actually helped create it

I'm curious Matt, is the original prototype still around somewhere?
