The Vertigo™ by Mono features a fully redesigned Headlock™ neck suspension system. No strapping, buckling, or belting required. No extra steps. Just throw your guitar in and the neck finds a natural resting point in the base of the Headlock™. Then zip the case up and the top section of the Headlock™ automatically clamps down over your bass, holding it firmly in place. Your headstock is now fully protected against backward drops and side-to-side impact. Lightning fast!
