Description
This is a trumpet mouthpiece design utilizing a UMI-Conn 10½CW rim, Vincent Bach 3F shallow cup, and Bach 3E 117 backbore, intended to complement the Lausmann-made Conn 10½CW. The overall sound is very bright and has great high note support.
The 10½CW was based on the Vincent Bach design but with a flatter rim, making it more comfortable than some of the radically-sloped rims found on Bach 10-1/2CW [10HCW 10.5CW] examples, especially newer ones. That medium-size, medium-depth cup is relatively standard for a middle-of-the-road trumpet tone - not overly dark or bright.
Bach generally uses different rims for different cup depths, even when they have the same nominal rim diameter, i.e. the 3 vs. 3C vs. 3E rim shapes. The 10¾CW & 10¾EW / 17C1 & 17C2, however, have very similar rims despite the cup and backbore differences. The 10¾EW provides a brighter sound and more upper register support, while the 10¾CW provides a broader sound at the expense of a scintillating upper register.
In the same way, this 10½FW s intended to be a shallower version of the Conn 10½CW, though the rim bite was adjusted slightly.
The backbore is the large Bach 117, intended for an open feel especially with piccolo trumpet. This is intended to reduce the stuffy, tight pressure feeling and nasal tone quality of narrow backbores. However, the shank opening is thinner and more fragile as a result, making this a candidate for metal manufacturing.
No dimensions have been adjusted or modified for printing or cutting. This model is intended for experimentation, with the price intended to offset scanning costs of the original mouthpieces.
The Conn 10½CW original is at Cults3D and Sketchfab for comparison. For verification, Overall length 87.63 mm / 3.450", and [greatest] outer diameter of 27.96 mm / 1.101".
Note that the shank opening is very thin and fragile with resin prints - be careful with this piece!
