Reginald Chapman Tuba+Bass Bone?

[Fruitysloth]

Hi all,

Has anyone tried these? Reggie is an amazing player, I might pick up the tuba mp for some doubling things, but I'm curious about the bass mouthpiece as well. Specs are on the page:

I haven't tried either of them, but the specs he mentions are almost identical to the pieces I play anyway - right down to the CV type cup. Marcinkiewicz 105 (CV) on bass bone at 29.4 MM inside the rim, and Sellmansburger Symphony model cup (CV) and backbore with a MO (Houser) Helleberg style large rim at 33.2 MM inside diameter on tuba.

The bass piece is maaaaaassive. I played his prototype at NAMM 2019. For me, unplayable (and I can play a 95D pretty convincingly if need be). Pretty odd design minus the size, as well. It works for Reggie, I'm not sure about everyone else.
