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
The narrowest trumpet size in Schilke's Heavyweight line. Less lip vibrating means easier control, less volume ceiling.
Detail 02
Rounder than the semi-flat 4 rim. Easier to move on for flexibility and fast response, at the cost of some upper-register comfort.
Detail 03
Deeper than the shallow A cups in this line. Gives the small diameter enough cup volume to produce real tone.
Detail 04
Schilke's standard trumpet throat. More open than the tight 27 used on their lead pieces, tighter than the 24 on the Symphony M models.
Detail 05
Extra mass in the blank versus the Standard Series. Same dimensions inside, noticeably heavier and more solid in the receiver.
Detail 06
The premium finish, and most of why this costs what it does. Dimensionally identical to the silver version.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It's the smallest diameter Schilke offers in this line at .665 inch. Players moving from a standard 7C-size piece will notice a tighter, more confined feel on the lip.
The 13 sizing is aimed at developing players, but this is the gold-plated Heavyweight blank. You're paying for the finish and the extra mass, not the dimensions.
Just mass. The cup, rim and throat match the standard 13. The blank has more metal around it, so it sits heavier in the horn.
It isn't built for that. Schilke's high-register pieces use a shallow A cup, a number 4 rim and a tight a-backbore. This has a C cup, a 3 rim and a 26 throat.
