Detail 01
The middle chamber size in the Graftonite line. Balanced response rather than the brightest or darkest option.
Detail 02
Mid-range for the line. Takes more air than a 3, gives more volume and pitch flexibility.
Detail 03
Consistent piece to piece and survives drops that would crack hard rubber. Easy to justify as a backup.
Detail 04
Bore and shank are sized for soprano necks only. It will not fit alto, tenor or baritone.
Detail 05
Cheap enough to keep a spare in the case, or to own two tip openings.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
B is the chamber size, the medium of the three Graftonite chambers. 5 is the tip opening, mid-range for the line. Together they set how much air it takes and how flexible it feels.
It fits standard soprano sax necks. It will not fit alto, tenor or baritone, and it is not a clarinet piece.
Most players land on 2 to 2.5. The 5 tip opening is fairly open, so harder reeds get stiff quickly. Move up only after your embouchure settles.
Usually yes on consistency and tip opening, since stock student pieces tend to be closed and tight. It is still molded plastic, not a hand-finished piece.
