What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
0.429 in. cup depth, compared to a Bach E cup
A shallow cup. Brighter, quicker response, easier high notes, less low-register weight.
Detail 03
Medium round rim
No sharp bite, no overly wide cushion. A middle-ground contour most players adapt to quickly.
Detail 04
0.144 in. throat (drill/venturi)
A tighter throat than standard. More back-pressure and resistance, which helps control at the top.
Detail 05
3.450 in. length
Standard trumpet length. Drops into a normal Bb or C leadpipe with no intonation surprises.
Detail 06
1.081 in. outside diameter
Standard shank size, fits typical trumpet receivers and standard mouthpiece pouches.
Final check
Know before you order
- 01Shallow cups reward a settled embouchure — switching mid-season can cost you
- 02Sold as the mouthpiece alone, no pouch or case
- 03Tighter throat feels more resistant if you're coming off a wide-open piece
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How does this compare to a Bach 7C?
The rim is a touch narrower and the cup is considerably shallower — a Bach E cup depth. Expect a brighter sound and easier high register.
02Is this good for a beginner?
Not really. The shallow cup and tight 0.144 in. throat suit developed players. Beginners usually build tone better on a medium-depth cup.
03Will it fit my trumpet?
Yes for standard Bb, C and flugel-free trumpet receivers — it uses a standard trumpet shank at 1.081 in. outside diameter.
04Can I use it for jazz combo playing?
It works, but it leans bright and forward. For a rounder combo sound, a deeper cup gives more warmth in the middle register.
