An "all-purpose" F tuba mouthpiece is a mouthpiece that will allow you to do everything you want to do on a F tuba - at least that's how I define it. If you meant to ask for specific examples - depends on what types of music you play, what your concept of sound is and what your expectations are - I mean, it depends on what you want out of a mouthpiece - for your F tuba.
Personally, I think the Perantucci PT-65 is just a terrific mouthpiece for F tubas, if you want something bigger, a PT-72 is also a great mouthpiece, PT-80 is about as large as I'd go for F tuba, which is a very comfortable mouthpiece, and works well with smaller CC tubas, like the Miraphone 186. Schilke 69C4 is very good also.

Again, An "all-purpose" F tuba mouthpiece is a mouthpiece that will allow you to do everything you want to do on a F tuba, if solo is a lot of what you do on F tuba, a Yamaha Roger Bobo solo will fit nicely, too. Just some personal experiences.


Sheridan line mouthpieces - I only have experience with the S3, which I did not like so much on my Miraphone 181 F tuba, but did have a comfortable rim and has a nice cup/throat/bore balance, it was a nice friendly mouthpiece.

Adam,

What kind of horn are you playing on? Blaine Cunningham recently wrote me and told me a Marty Ericksom ME2 was the mouthpiece he used on his F tuba all the time. I know he plays his willson F in wind ensemble and for solo work.

I play a 45slp and was trying to find a place close enough I could go to try out just about every different F tuba mouthpiece there is in the world.
