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 Group I range. Enough lip in the cup for tone, not so wide that a developing embouchure struggles.
Detail 02
The standard cup depth here. More volume than the A and B cups, so the sound has body rather than edge.
Detail 03
Schilke's standard rim. Rounder than the number 4, which makes slurs and flexibility easier.
Detail 04
Notes speak fast and lip slurs move freely. Trade-off is less cushion on long sets than a semi-flat rim.
Detail 05
The standard throat across most of this group. Normal resistance, nothing unusual to adapt to.
Detail 06
A finish choice only. Cup, rim and throat dimensions match the same model in other finishes.

Product questions
Straight answers to the questions shoppers most often ask about this product.
That's what it's built around. The .665-inch cup, standard number 3 rim and C cup give a developing player quick response, easy flexibility and enough cup volume for a full tone.
Same .665-inch cup diameter and 26 throat. The 13 uses the rounder number 3 rim; the 13C4 has a sharper inner edge and a number 4 semi-flat rim that adds endurance.
It isn't set up for it. The C cup is a full-depth cup built for tone. The A cup models in this group, like the 13A4a, are the ones aimed at upper register work.
The 14 is wider at .670 inch versus .665, with a standard rim, cup and backbore for all-around playing. The 13's rounder rim favors flexibility and quick response.
