What matters in use
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 01
Mid-sized in the SM range. Wider than the 5 and 6, narrower than the 2 — more sound without losing high notes.
Detail 02
Slightly larger than the smallest SM throats. Lets more air through, so the sound opens up but takes more support.
Detail 03
Tapered rather than barrel-shaped. Tends toward a rounder, more centered tone versus the wider-open barrel designs.
Detail 04
Moderately narrow rim. More flexibility and pitch bending, less cushion on long rehearsals than a wide rim.
Detail 05
Feels warmer and slightly grippier on the lip than silver. The usual choice if silver irritates your skin.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
The 3 has a slightly wider cup at 26.40mm versus 26mm, with a marginally wider rim. The 4 is a touch smaller and leans toward upper-register clarity.
Denis Wick makes this size in both medium and large shank. Measure or check your instrument's receiver first — the wrong shank will not seat properly.
Not tonally. It's about feel and skin contact. Gold is smoother and warmer on the lip, and is the option for players who react to silver.
Yes. It's a professional-line piece with a defined cup, rim and throat, priced accordingly. Expect a different response than a factory-supplied mouthpiece.
