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
Bigger diameter means more volume and a fuller low register, but costs endurance. Smaller favors high notes and stamina.
Detail 02
Barrel gives a rounder, more centered symphonic tone. V-type opens projection and makes the upper register speak more easily.
Detail 03
Wider rims spread pressure across more lip and extend endurance. Narrow rims give sharper articulation and more flexibility.
Detail 04
Larger throats blow freer and take more air. Smaller throats add resistance, which helps control at lower volume.
Detail 05
Feels warmer and slicker on the lip than silver. Softer than silver, so it wears through faster with heavy use.
Detail 06
E models are bright, high-register lead pieces. X models add an extra-wide cushion rim for comfort over long sets.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Both are 16.50 mm with a 5.18 mm rim and 3.70 mm throat. The 4 centers pitch with a warm, dark tone; the 4C is harmonically richer with a stronger high register.
The 4B. It uses the same 16.50 mm cup as the other 4s but is built to blow easily with a warm tone, so it does not fight a developing embouchure.
It is not better, just different. Gold feels warmer and slides more on the lip, which some players prefer. It is also softer and wears faster than silver.
The 5E is the brightest screamer of the group, with a 16 mm cup and V-type backbore. The 3E and 4E are similar but with progressively larger cups.
