Mono M80 Double Electric Guitar Gig Bag (Black)Double TroubleA second guitar is a must have on stage or in the studio. But in transit, carrying two 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 and patented. The end result is an incredibly light weight, extremely rugged double hybrid case.
