Now it is finally possible to carry one semi-hollow and one solid body electric guitar at the same time, both fully protected with MONO's patented Headlock neck suspension system. A first of its kind. Go play. The patented “zig zag” design of the Classic Dual Semi-Hollow/Electric Guitar Case creates a completely separate case for each guitar. Load your archtop or semi-hollow guitar in first. The electric guitar slides into its own slim, Sleeve-like compartment. Both are protected with our Headlock suspension system and strap pin bumpers. Both are always easily accessible and the case can be used with one or two guitars.
