The Classic Acoustic/Dreadnought Guitar Case can be found in the hands of influential musicians from Brooklyn to Seoul to São Palo and everywhere in between. Its patented protective features and light weight hybrid shell revolutionized the way we travel with our guitars, and brought musician luggage into the 21st century. Years of feedback from working artists has driven countless tiny improvements, proving that this original design just gets better with time. If you own a guitar, you should own a MONO. The patented Headlock™ design provides a level of protection worthy of the finest instruments. Your guitar quickly straps in and remains stabilized during transport. The headstock is suspended inside the case, saving the guitar from both side and rear impacts that could otherwise snap the neck. The result is a super light case that is ready for anything life brings. Hi-density foam bumpers divert vertical impacts out and around the lower bout of the guitar, away from the strap pin. Integral ABS panels deliver hardcase protection at a fraction of the weight. (MONO cases weigh in at about 75% less than their hardcase counterparts.) The reinforced outer shell of the M80 hybrid case absorbs and deflects hard impact away from the vulnerable areas of the guitar.
