Rim and cup similar to 7C
With the symphonic backbore (E) and the throat 3.80mm we get a mouthpiece with a very big sound. This makes this mouthpiece ideal in the symphonic repertoire. Romera Brass sound.
Inner rim diameter: 16,25mm
Outer rim diameter: 27,40mm
Cup depth 10mm / Throat 3,80mm / Nº 25
C medium Symphony.
Makes easier the high registers and helps to focus the staccatto.More brilliant than E open Symphony backbore and with a sound with a lot of projection. Similar to V.Bach Backbore.
E open Symphony.
Backbore for all the symphonic repertoire. Powerful and big sound but without losing sound projection. If having problems with high registers or in focusing the staccatto, better choose the C medium Symphony backbore.
Rim shape options:
B sharp inner rim Similar to the classic American but more comfortable
L rounded inner rim shape
