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
Hard reed. Needs solid air support and a settled embouchure. Rewards control, punishes an unformed one.
Detail 02
The filed shoulder makes response quicker and the tone brighter than an unfiled reed of the same number.
Detail 03
Cane varies piece to piece. A box lets you break in several and keep the two or three that play best.
Detail 04
Cut to soprano vamp length and width. It will not seat properly on an alto or tenor mouthpiece.
Detail 05
Reacts to humidity. Reeds swell when wet, warp when dried unevenly, and lose life over weeks of playing.

Product questions
Straight answers to the questions shoppers most often ask about this product.
If you play 2.5 or 3 comfortably and want more resistance, step to 3.5 first. Jumping straight to 4 usually means a thin, strained sound until your embouchure catches up.
No. These are cut for soprano saxophone. Alto reeds are wider and longer, and the two are not interchangeable.
Depends on hours played and rotation. Rotating three or four reeds from the box rather than playing one to death stretches the whole box considerably.
Royal uses a filed cut, which speeds response and brightens tone compared to the unfiled standard Rico of the same strength.
