This is a very modern design that features a large bell, large bore BBb tuba with a compact wrap. Because of that some might call it a 4/4 or a 5/4 size tuba, which is just a matter of opinion. So, you can refer to it as a relatively large bore 4/4, or a compactly wrapped 5/4. Besides the large bore, the 5/4 proponents look at the large bottom bow and large bell throat which makes this a decent big larger than a 4/4 186 tuba. The Phoenix TU-BBb-4R1 has four rotary valves, a brass body with nickel leadpipe and bell kranz, and nickel trim. It is available in all gold brass as well. If you prefer a broader sound and a larger feeling horn that's still nimble, I think this is a big improvement over many of the more common slotting problems of Tubas, this is an excellent choice without compromising either slotting or tone. It is much more flexible and less harsh than almost any other Tuba in its class. While it has a very traditional fast response, it holds together very well when you play with more volume. This professional quality instrument has an amazing low range. The low notes simply flow of out this horn with strength and body without ever sounding brittle.
The valve linkages on this model are very quiet, absent of rattle. This horn has a large 18.5" (470 mm) bell and a constant bore through the valves of .787" (20 mm). A soft, hard foam, canvas case is included, but you could also purchase a hard case such as the new SKB385W.
This tuba is often compared directly with similar models from Miraphone.
