Alexander tubas 2.jpg
Mike,
Good questions that are almost impossible for me to answer with any certainty - because I have never played a Bb 164.
Alexander has been making both BBb and CC 164's for over 100 years (see photo). There is some "myth" around BBb's being cut into CC's causing the intonation problems found.
As with many CC tubas, G first line is typically flat. This is the case on all three of my Alexander CC's. Having the first slide shortened by an inch, I can now play that G one and three in tune. Because the "kicker" is so well engineered, it's much easier to move the main slide with the kicker than fuss with moving the first valve slide - so F below the bottom line of the staff and Bb second line are brought in tune with the main slide kicker - if that makes sense. It's logical that the BBb 164's have related pitch issues, a whole step lower. (Eb, F, Ab)
The bigger the tuba and bore size, the bigger the intonation problems - generally. As I stated earlier, everything is magnified from the 163 - including the amount of sound. Sitting behind the 164 and playing it, to me it feels like twice the sound as a 163. It's MORE - and it's so far, exactly what I've been looking for.
Of course I would love to play a BBb, just for grins and comparison to the CC - but I doubt I'll ever have two 164's in the same room. And even then, does a 5 valve BBb exist? I've been calling the 164 a "unihorn" - a mythical beast that really does exist. The level of craftmanship on my 2004 164 is astounding. Alexander only builds what is bought - they don't produce inventory. You can't go to Mainz and play a dozen 164's. If there is anything to play, consider yourself lucky. My overall point is this model shouldn't be dismissed because of stories heard. The 164 is not a point and shoot tuba - they take time and patience, the same as the 163's and the F tubas. The reward for the investment of time and patience is a sound that is clear, rich, and unique.
