Having a second bass is essential for the stage or studio—but transporting two has always been a challenge. That’s why MONO set out to create a smarter, sleeker solution. The goal: deliver the same high-level protection as the single M80 hybrid case for both instruments. After a year of meticulous prototyping, the patented Z-form™ design was born. The result is the Classic Dual Bass Guitar Case—ultra-lightweight, incredibly durable, and purpose-built to carry two basses with ease. A true first-of-its-kind for bassists on the move. 360° PROTECTION DROP-PROOF The patented Headlock® design provides a level of protection worthy of the finest instruments. Your guitars quickly strap in and remain stabilized during transport. The headstocks of both guitars are suspended inside the case, saving them from both side and rear impacts. STRAP PIN PROTECTION Hi-density foam bumpers divert vertical impacts out and around the case, away from the strap pin. Integral ABS panels deliver hardcase protection at a fraction of the weight. The reinforced outer shell of the case absorbs and deflects hard impact away from the vulnerable areas of the guitar. SMART STORAGE ONE OR TWO GUITARS This patented “zig zag” design creates a completely separate case for each guitar. That means both headstocks are protected with our Headlock® suspension system and strap pin bumpers. It also means the M80 Dual can be used with 1 or 2 guitars - something you’ll appreciate on the road. Additionally, the Z-form design allows for immediate access to either instrument. TICK-READY Most MONO cases come equipped with the triple D-ring attachments required for the optional Classic Tick Accessory Case, the modular tool case designed to extend the storage capacity of your guitar case. The Classic Tick Accessory Case seamlessly and securely attaches to the case as shown. Some older cases may not be Tick-ready - please contact support if you have questions about the Tick-compatibility of your MONO case. PLUG AND PLAY Everything in its place. Specialized storage compartments put your gear right where you need it. The hidden upper pocket keeps your wallet, keys, and cell concealed. Pen slots double as tool storage. Business card storage and a durable key clip are also included. BUILT TO LAST WEAR IT OUT We build our cases to military specs, using only high-test materials with extreme resistance to abrasion and the elements. Inside, the plush lining protects delicate custom finishes. Outside, the water-resistant Sharkskin™ shell keeps you on the move, rain or shine. 100% animal free. RIVETED HANDLE & HYPALON SOLE Rock solid, industrial webbing handles come standard on MONO cases. Bar-tack stitching and steel rivets reinforce for strength, while high grade webbing provides a super comfortable grip. All M80 cases feature a hard-wearing sole and piping made of Hypalon - the same industrial rubber used to create inflatable military rafts. This sole simply does not wear out Internal Dimensions: 48 x 14.5 x 3 (121.9cm x 36.8cm x 7.6cm) External Dimensions: 49.2 x 16.9 x 4.7 (125.0cm x 42.9cm x 11.9cm) External Pocket Dimensions: 11 x 14.5 x 1.5 (27.9cm x 36.8cm x 3.8cm) Weight: 9.92lbs (4.5kg)
