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

Re: Conn 52J CC tuba
I'm curious Matt, is the original prototype still around somewhere?

If at first you don't succeed, skydiving's probably not for you.
