DIFFERENT OR SAME MOUTHPIECE?

[Ben]

Do you use different mouthpieces on different horns[?]

yes, and - in one case (even though still a "tuba") - not even the same rim.

ditto, 4 horns, 4 MP's with a few (3) alternates for trade-off attributes (rims/cup shape/size).

No.

Bach 18- all tubas, 95% of the time.
JK KBP2C- contrabass trombone all the time, bass trombone almost all the time.
Yamaha 60B- big tenor all the time, some jazz bass.
Euph is usually 3gish, sometimes 60B. That 2C is my favorite mouthpiece for anything ever.

Do you use different mouthpieces on different horns or the same mouthpiece on all of them that you play?

No. I use a blokepiece solo#2 with the small helleberg rim for both my CC and my Eb/F. However, My CC is the big 6/4 CC tuba so a small F tuba piece works very well on that horn. If I had a 4/4 or 5/4 CC I wouldn't use my F tuba mouthpiece on them. So currently no but I would if needed.

I use different mouthpieces on each horn. I tried many different mouthpieces with each horn to find one that gave me what I thought was the best combination of range, sound, and intonation on the horn. I have pared down the number of horns that I play regularly to just 2, a King 2341 (one piece) and a Besson 983. The Besson is very mouthpiece sensitive in terms of intonation, and the mouthpiece that allows me to play in tune for it is much too bright on the King. I also have a Conn 40K and I use a different mouthpiece for that. When I had many more horns I tended to match a mouthpiece to the horn and stick with it on that instrument rather than using the same piece across all of them.

I use different mouthpieces but keep matching rims (same size, shape, contour, etc ad nauseum.) I know Chester Schmitz and Alan Baer both apply this same rule.

[Gilligan]

I'll second the different mouthpieces but same rim idea.

I'm using Bloke's Imperial mouthpiece for my Besson Eb Soverign and his Symphony for my Schiller BBb both with the Fair Dinkum #2 medium round rim. Keeping the rim the same improves my accuracy on both horns.
