v.1 - Most like the original and the blow will feel similar, although the mathematical path is cleaned up. A very high alpha, flat rim, soft bite, a bore that is a little smaller than a #24. Very open blow and you must respect that high alpha angle. The alpha angle can support your chops or stop them from vibrating if too much pressure is used. Most lead mouthpieces are between 15 and 24 degrees, an extremely high alpha is about 28 degrees, this model is close to 40 degrees. GR #2 Backbore and length.

v.2 – The rim and alpha angle the same as the v.1. This has a blow that works well with the modern day trumpets, it has a #27 bore, GR throat entrance that is longer and allows the mouthpiece to play better in tune and will help endurance even with larger bore or more open horn. Often players tend to go sharp on the original with the horns made today, due to the high alpha angle the lip engagement may be an issue. Added pressure leads to a very small cup volume left after the lips have engaged. The length of the mouthpiece with a non-linear shape doesn’t determine pitch. The volume determines the pitch. As the lips engage and reduce volume the upper register can go sharp, also the larger 24 bore will raise the pop pitch frequency of the mouthpiece. Therefore, in the v.2 we reduced the bore to bring pitch down a bit and added a little resistance to balance the lip engagement. GR #2 Backbore and length.

V.3 – This is the same basic rim. The rest of the parameters are redesigned with a lower alpha angle in the low 20’s and a bit more room yet giving the same powerful sound in the upper register and fatness in the lower register. GR #1 Backbore and length.

Flugelhorn version of the G.O.A.T.  Scare them with the G.O.A.T trumpet piece, woo them with the G.O.A.T flugel. Big, fat, fluffy, push it and it can sound mean or lay back and feel those overtones.
