The Miraphone M7000 Ambassador EEb Tuba includes a lot of the same features of the M9000 Amabassador BBb. The features include a .709-inch to .740-inch conical bore plus a 4 valve (3 Top and 1 Side) compensating valve design that is an excellent choice for brass band work. The Ambassadors nickel silver mouthpipe offers a quick response for this 5/4 instrument.
The Meinl Weston 2141 Eb tuba is an amazing instrument. At a 5/4 size with the large valve set this horn can produce a very strong sound in all registers. The 17.25" bell adds a lot of resonance as well. Add to this the 5 valve features and you have an unbeatable combination.
