CC's: 186 or 188..?

What's the difference out front that a listener might notice if these two horns were played back to back, by the same player with the same mouthpiece?

Nothing really. The 188 might sound a teeny tiny bit bigger. This might depend on the vintage of the 186 since they've been around forever. I'd bet that very few listeners could tell the difference between a 186 and 188 of the same vintage and same brass type (ie, both yellow brass or both gold brass).

If somebody could identify the years that Roger Bobo played a 186 with the LA Philharmonic and compare recordings with the years he played a 188, that could actually give you something real to compare... same player, different equipment. Of course it might ignore other variables along the way too.

The 188 typically has a better intonation and is a bit larger tuba.
The 186 typically has the better responding low register.

If I were choosing, I'd get a 188.

I'd have to agree with this statement. I really doubt a typical audience member can really hear much of a difference, except that a really critical listener might hear it as a little more broad sounding. Try them both - you should be able to find a 186 and a 188 to a/b . . . they're pretty easy to find, as far as CC tubas go. Both very nice horns, IMHO. as close to a "do it all" horn as one will find.

Why?? You thinking about CC-ing it??
