Who the PB304CTXL Alto Saxophone Case Is For
The Protec PB304CTXL is a contoured protective carrying case for alto saxophonists who need a secure fit for vintage horns or modern altos with larger bells or alternate key layouts. It is designed for musicians who want the impact protection associated with a wood-frame case while keeping practical storage and carry options typically found on gig bags.
Key usability features include a QuickLock closure for securing the case when empty without zippering, strong metal hardware and custom zippers (with a lock hole on the main compartment), reinforced rubber feet and rubber runners for corner and zipper protection, and two large storage pockets. The front pocket is gusseted for accessories and includes a built-in organizer with pen sleeves and zippered compartments; the rear pocket is sized for sheet music. The interior separates the neck and mouthpiece to help prevent dents and scratches, and the mouthpiece section accommodates large ligatures.
