Winner - Music Makes a Difference Award

Mellow and easy to play
Different people have different tastes and needs so we decided to offer three standard levels of depth, what we call "shallow" (comparable to the depth of a Bach for flugel), "normal" (as deep as a Yamaha) and "deep" (as deep as a Denis Wick).
Here's how our sizes compare to Bach sizes:
VL = Bach 1 17.40mm
L = Bach 1-1/4 17.20mm
ML = Bach 1-1/2 17.00mm
M = Bach 3 16.80mm
MS = Bach 5-7 16.60mm
S = Bach 10-1/2 16.40mm
VS = Bach 15 16.00mm
XS = Bach 17-18 15.60mm
Each cup is available with any of our rim diameters and shape, throats are either 42 (#19) or 46 (#14). We prefer matching the big throats to deep cups to have that typical European super dark sound. Shallower cups and tighter throats can be useful for those that mainly play trumpet and occasionally double on flugel.
Backbores are available with small (Bach), big (Yamaha) and Couesnon shanks with our usual Small, Medium and Large sizes.
