Detail 01
Size 1 rim
The largest common Bach rim diameter. More lip vibrates, so the sound broadens and the low register opens up.

BachStandard Series Trumpet Mouthpiece in Silver 1CW
Independent shopping perspective
The Korena take
Bach 1CW trumpet mouthpiece — a very large rim with a cushioned edge, for players who want maximum low-register support.
Strong match
Who this is for
- Players wanting a big, dark sound in the low register
- Symphonic and concert band trumpet parts
- Players whose lips fatigue on sharp, narrow rims
Consider the trade-offs
When to look elsewhere
- Lead trumpet players chasing high notes
- Beginners — a 1 rim is a lot of horn to control
- Cornet — the shank taper is different
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
W rim shape
A wider, more cushioned rim contour. Spreads pressure across the lips and takes some sting out of long sessions.
Detail 03
C cup depth
Bach's medium-deep standard cup. Warmer and fuller than a shallow cup without going as dark as the deepest options.
Detail 04
Silver plating
Slightly slicker feel than raw brass and resists tarnish. Some players react to silver on the skin.
Detail 05
Trumpet shank
Fits standard trumpet receivers. Cornets use a narrower shank and will not accept this.
Final check
Know before you order
- 01Mouthpiece only — no pouch or brush included
- 02A 1 rim is a big jump from a stock 7C — expect a real adjustment
- 03Endurance drops before it improves when moving up in rim size
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How does 1CW compare to a 7C?
Much larger rim. The 1 gives a broader sound and stronger low register, but demands more air and more embouchure control than a 7C.
02What does the W stand for?
It marks a wider, cushioned rim contour. Same cup and diameter family, but the rim edge is rounder against the lips.
03Will this help my high notes?
Generally no. Larger rims and medium-deep cups favor low and middle register power. Lead players usually go smaller and shallower.
04Is silver plating better than gold?
Different, not better. Silver feels slightly firmer and more slick. Gold is softer to the touch and is an option for silver sensitivity.
