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
Middle of the Steven Mead sizes. Room for a large sound without the air demand of the 27mm models.
Detail 02
Wide bore passes more air, so more volume is available — but there is less resistance to lean against.
Detail 03
Tapered cone rather than a straight barrel. Pushes the tone warm and round rather than edgy.
Detail 04
These come in large and medium shank. Your euphonium's receiver decides which one seats correctly — it is not a preference.
Detail 05
Wide and cushioned. Helps endurance through long solo passages, slightly softens the definition of attacks.
Detail 06
Softer and warmer against the lip than silver, and the usual fix for players who react to silver alloys.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Gold is softer, warmer to the touch, and avoids reactions in players sensitive to silver alloys. The tonal difference is minor; feel and skin comfort are the real reasons to pick it.
Your instrument decides. Pull your current mouthpiece and match the taper, or check with the horn's maker. The wrong shank either falls in too far or won't seat.
The 4 is 26mm with a slightly narrower rim and leans toward clarity up top. The 3 is 26.40mm, set up for solo projection and a warm, clear tone.
No. It's cut for euphonium — the cup is too large for baritone and the shank may not seat properly in the receiver.
