The Robert Tucci RT-84S tuba mouthpiece can work well with any tuba, but is actually known as being a great option for Eb tubas.  The RT-84 can produce power that is balanced with color.  The overall sound produced from the 84 works well in chamber, solo, and large ensemble settings where nimble playing is required.  The rounded rim provides comfort and endurance.  The RT-84 is a classic design from Bob Tucci that provides comfort, ease of playing, and a clear but resonant tone.
