6/4 recording tubas produce false tones even more easily and more solidly than regular 6/4 tubas (in my experience), so - as one of your tubas has three valves - that's the one to feature three.

... same goes with 5/4...Unlike most people who own old Besson tubas, I have both a 24-in recording belt and a 17 inch upright bell for my compensating Besson B-flat. The false tones are much easier with the recording bell offering the additional curve at the end of the instrument.

That's a nice pair of instruments you have there!

Wondering out loud… in text… I wonder if that bell-elbow-curve reflects the sound back in a bit allowing it to be pushed against resulting in better false tones?

Maybe we need a “Show us your bell front tuba” thread.

Okay, I found a mouthpiece combo this tuba really likes.

@bloke piece Symphony, with an Orchestra Grand Euro shank.

False tones... YEAH!!! This thing eats them up. I played it a bunch today, and pitch/response stability is MUCH better on this one than my original-ish condition 340.

Once that thing goes together with some care, I think I'll have some dangerous weaponry on my hands. Rebuilt valves, carefully soldered together, dent free, raw brass... Drool.
