Mono M80 Bass Guitar Case
The Mono M80 is a professional-grade bass guitar gig bag designed to offer high-level protection through a hybrid construction of semi-rigid materials and high-density padding. It features a patented integral headlock design and impact-deflecting bumpers to secure the instrument during transport.

Overview and Design
The Mono M80 Bass Gig Bag in Black is a high-performance transport solution for bass guitarists. It occupies a space between a traditional soft gig bag and a heavy hard-shell case, offering the portability of the former with the structural integrity of the latter. The exterior is constructed from durable, weather-resistant materials designed to withstand the rigours of touring and frequent travel.
Integral Headlock Technology
A primary feature of the M80 is the patented Headlock design. Inside the case, a specialized neck support system suspends the bass guitar's headstock and neck, protecting them from backwards and side-to-side impacts. This design includes a clear window pocket specifically intended for storing a variety of guitar picks, ensuring they remain accessible during performances.

Vertical Impact Protection
To address the common risk of drop-related damage, the M80 incorporates high-density foam bumpers around the bottom of the bag. These bumpers are engineered to deflect vertical impact away from the strap pin and the body of the instrument. This specialized cushioning creates a protective buffer that prevents the guitar from hitting the ground directly if the bag is dropped upright.
Ergonomics and Storage
The bag is equipped with a dual shoulder strap system, featuring both left and right straps to distribute weight evenly across the player's back. This makes it suitable for long-distance commuting. In addition to the internal pick pocket, the M80 typically includes external storage compartments for cables, tuners, and other essential accessories required by professional musicians.
Market Position and Alternatives
At a retail price point of approximately £229, the Mono M80 is positioned as a premium accessory. While more affordable options like the Latin Percussion LP Cajon Bag or Gear4Music Rock Fusion Drum Bag sets exist for different instruments, the M80 is a specialized tool for bassists. It provides a level of protection comparable to high-end orchestral cases, such as the BAM Conservatoire or Artisto series, but tailored for the specific dimensions and weight of a bass guitar.
