YamahaStandard Trumpet Mouthpiece 14B4
1/8
Independent shopping perspective
The Korena take
Yamaha's 14B4 standard trumpet mouthpiece. Medium rim with a shallower B cup, aimed at players who want easier upper register than a stock 7C.
Strong match
Who this is for
- Players stepping off a standard 7C wanting more high range
- Lead and commercial work needing a brighter attack
- Marching players who need projection outdoors
Consider the trade-offs
When to look elsewhere
- Orchestral players chasing a dark, broad legato tone
- Beginners still building embouchure — a deeper C cup is easier
- Cornet or flugelhorn players; this is a trumpet shank
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
B cup depth
Shallower than the common C cup. Brighter tone, less air needed up high, less body in the low register.
Detail 03
4 backbore
Yamaha's standard backbore across the line. Keeps resistance even so the horn feels normal, not tight or wide open.
Detail 04
Comparable to Bach 3C / Schilke 15B
If you already play a 3C, the rim will feel familiar; the cup will feel shallower and brighter.
Detail 05
Yamaha standard series
Machine-cut to a fixed spec, so a replacement in five years plays identically to this one.
Final check
Know before you order
- 01Trumpet shank only — will not fit cornet or flugelhorn receivers
- 02Rim change from a 7C takes a week or two to adjust to
- 03Shallower cup thins the low register; keep your old piece for deep parts
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How does the 14B4 compare to a Bach 7C?
The 14B4 has a wider rim and shallower cup. Expect easier high notes and a brighter sound, with less depth below the staff than a 7C.
02What Bach mouthpiece is this closest to?
The rim is close to a Bach 3C. The cup is shallower than any C cup, so the overall feel sits between a 3C rim and a lead piece.
03Will this fit my cornet?
No. Cornet receivers take a shorter, narrower shank. This is cut for trumpet only.
04Is this a good first upgrade from a student mouthpiece?
Only if you already have a solid embouchure and want more high range. Developing players usually do better staying on a deeper C cup first.
