The "Goz" - Conrad Gozzo
(Description by Gary Radtke)
This is a very unique mouthpiece. Story has it that it was a modified 7C by Bert Herrick. I have seen 2 very old Bert Herrick mpcs that were suppose to be just like Conrad Gozzo's. They had similarities but were not 100% the same. If this was a modified old 7C, it was shortened and the rim was cut off. The Rim is wide and I would say cushioned, with a sharp bite, although, the profile makes it feel like a larger mouthpiece.
The cup is moderate, close to the volume of a GR M cup, the alpha angle is higher than the standard M cup, although, similar to the GR 64.7M.
The big key is the throat exponent makes this a very open mouthpiec and probably better suited to a trumpet with characteristics to those of the 40's, 50's, and 60's. You may have trouble with a really open horn. The uses are this piece are vast; good on the smaller horns like Eb and even some love it on piccolo (rim is close to a "W" in width). This mouthpiece has a big fat sound for the right match player and horn.
