It was well received. Everyone thought it really beautiful in its red brass and the conductor (an ex-BBb player himself) commented that the Cerveny had that special 'gruff' BBb bass sound which my Neptune does not (the CC's sound is more lyrical). Although very different from the usual brass band Besson, it seems to provide a good tonal substitute.
I got on pretty well playing it, providing an apparent satisfactory foundation, while not once getting the hand - something which pleased me as I was concerned a Kaiser BBb might be too big for the band.
I enjoyed playing it, but didn't half feel tired after two hours - it certainly takes the air and provided a good work out. I have found previously that playing my big Neptune improves the subsequent playing of my smaller tubas. I reckon the CBB701 will have the same effect on my Neptune playing which will seem that much easier after the wider bored Kaiser.
Here are some pictures of my new BIG baby!

I have done some comparison measurements with my B&S 6/4 Neptune which I thought interesting (* = my approx measurements):
Height: Neptune (N) 39" (99cm); Cerveny (C) 44" (112cm)
Valve Bore: N 19-21mm (graduated) ; C 21.2mm
*Top Bow circumference : N 8.25"; C 9"
*Small side bottom bow circumference: N 10.5"; C 11"
*Bell throat circumference: N 19.25"; C 19"
*Circumference 12" below bell opening: N 26.5"; C 25.25"
Bell diameter: N 520mm; C 500mm
The Cerveny is larger bore right up to the bottom bow when the Neptune expands at a greater rate to the bell which I think is apparent in the picture. Maybe that is the defining difference between a Kaiser tuba and a 6/4 BAT?

Being the red brass version, the CBB701 has nickel silver fittings throughout, including the valve casings. I understand nickel is the best material for rotary valves for long reliable service. These are really fast, smooth and quiet with their minibal linkage. One thing I found to look out for playing a lot is that water builds up in the dip of the lead pipe, so if I tip the tuba back vertical to put on its stand I get a wet arm, or lap!

Comparing the back of the CBB701 and Neptune, the arrangement of tubes is almost identical, which rather makes me think the two models share a common ancestor, although from different companies.

I hope you enjoy the pictures. My impression so far is that the Cerveny is a very good tuba - I am thrilled with it
