A second guitar is a must-have on stage or in the studio. But in transit, carrying two bass guitars has always been a necessary evil. We set out to design an elegant solution to this problem. Our driving criteria was to offer each guitar the same protection as our single M80 hybrid case. After a year of prototyping, the Z-form™ design was perfected (patents pending). The end result is an incredibly light weight, extremely rugged double hybrid case. A first of its kind. Go play.
