Background and Design

The Gewa SPS Double Trombone Gig Bag is engineered for the professional trombonist who requires a secure method for transporting two instruments, such as a tenor and a bass trombone, or a combination of two tenors. Part of Gewa’s Side Protection System (SPS) range, it aims to bridge the gap between heavy, cumbersome hard cases and standard soft gig bags. The bag is constructed from Cordura 1680 Denier, a high-grade synthetic fabric known for its exceptional resistance to abrasions, tears, and water ingress.

Structural Protection

The core feature of this bag is the SPS system, which incorporates internal fibreglass or plywood reinforcement panels. A specifically padded plywood support is located in the bell area to prevent compression and maintain the bag's shape against impact. Furthermore, a five-sided plywood slide compartment ensures that the most delicate part of the trombone—the slide—is protected from bending or denting during transit.

Fit and Customisation

The bag is designed to accommodate instruments with a bell diameter of up to 9.5 inches, making it suitable for most standard tenor and bass trombones. To account for varying instrument dimensions, the bag includes adjustable inner padding. This allows the user to tailor the internal layout, ensuring that different models of trombones fit snugly without excessive movement inside the bag.

Storage and Portability

Beyond the main instrument compartments, the bag features a dedicated slide pocket and an accessory compartment for items such as mouthpieces, slide oil, and sheet music. The exterior design focuses on ergonomics, providing multiple carry options to suit the needs of the mobile musician, whether commuting or travelling between performance venues.
