.665 inch cup diameter
Comfortably medium in Schilke's lineup. Enough lip vibrating for a full sound without demanding a developed embouchure.

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
Comfortably medium in Schilke's lineup. Enough lip vibrating for a full sound without demanding a developed embouchure.
Detail 02
Deeper bowl than the A and B cups. More air volume behind the lips, so more tone and volume, less help up high.
Detail 03
Schilke's standard rounded rim. Rounder edges let the lips move more freely, which helps flexibility and fast slurs.
Detail 04
Standard bore. Opens the blow compared with the 27 throat on the shallow A-cup models, and evens out response across registers.
Detail 05
The rounder rim and medium diameter let notes speak fast — useful when a player is still developing attack control.
Detail 06
Firmer and slicker under the lip than gold. Cleans easily; a small number of players get a skin reaction to it.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes. The number 3 rounded rim and C cup give quick response and volume for tone, which is what a developing player needs most.
The 13A4a is narrower at .660 inch with a shallow A cup, semi-flat rim and tight backbore — a lead piece. The 13 is a general-purpose medium.
The 13B is .660 inch with a B cup slightly deeper than the 13A4, plus a narrower round rim. The 13 has a wider .665 rim and a C cup.
Not directly. The C cup favors tone and volume. If range is the goal, Schilke's A-cup models with tight backbores are built for that.
