1922 Holton Silverplated Mammoth BBb 3v - Bach 18 gold plated (excellent fit for over 30 years)
2006 B&S 3103 Anniversary Edition - PT-88 hand picked at Bob Tucci's shop (had a PT-88 with a VMI 3301 in 2001 and didn't like the tone or fit on my face)

[Mark E. Chachich]

Alexander 163 CC - Bach 7 modified for an Alexander
Meinl-Weston 32 CC - Bach 7 and Bach 18
York Monster E flat - Bach 32E

The contrabass tuba is my main instrument and the the Bach 7 is my main mouthpiece for the contrabass tuba.

I have played the Bach 7 for about 25 years, the Bach 18 for about 37 years and the Bach 32E for about 1 year

Concert tuba- generally Marcinkiewicz Rose/Schilke 66 depending on my mood and my chops

Sousaphone- A custom mouthpiece I put together while interning at a machine shop with a large diameter extreme funnel cup, an ultra flat and sharp rim, and an undersized backbore. It takes quite a bit of getting used to but it dramatically improves stuffy and unresponsive horns and really lets you put the volume to 11 when you really need it.

My large titanium custom piece made by G&W copied from a custom brass Zottola piece. It is an extra deep (AAA at least) with an almost flat bowl shape and a 9 mm. backbore. The inner rim diameter is 1.391" or approx 35.33 mm. The outer rim diameter is very close to 2". The rim is a bit rounded - similar to the Bayamo. The brass Zottola which I also use is gold plated and its rim is slightly larger and more rounded. I take them both to gigs and play the one which feels the most comfortable at the time - sometimes switching more than once during the long gigs. I also have a custom H.L White gold plated brass piece made in 1920's from a 2.25" brass stock. The cup is bowl shaped and not as deep as the other two. The inner rim diameter is close to 36 mm. and the rim is a little wider and rounded similar to the Zottola. I sometimes put this one in the rotation as well, as well as my Dr. Young extreme funnel made by Reynolds. Each of the mpc's has its own tonal character and they all work well in my 6/4 Holton BBb, 20J Conn and 5/4 BBb Rudy Meinl. I used both the Zottola and H.M White many years ago in both a Yamaha 381S Eb and the 3+1 compensating Besson Eb - the upper register tended to be a little flat and required some lipping up. Needless to say, the titanium and Zottola are very dark, which I like.

Yamaha Canadian Brass Signature on a Lidl 701 BBb (3/4). Beautiful sound, excellent low range, ok high range. I'm not yet sure if the mouthpieces i tried have any effect on intonation. With a Bach 18 replica the high range feels a little more secure, may be thats because its more of a bowl shape?
