I've been using the Mono Vertigo Bass for a while now and just got the Mono Tick to go with it, so here's my opinion: First of all, I don't really like hardcases. They're bulky, heavy and if you always take you bass out of the van on tour as I do, they're terribly difficult to move in small hotel rooms and elevators. While they offer good protection, a good padded gig bag will do the ob if the bass goes on top of the other gear in the van. Also, if you play internationally and use air travel, you always encounter the same problem: they won't let you take a hard case (or even a bigger gig bag like my protection racket) on the cabin. Small, light bags (i used to have a Warwick Rockbag Deluxe) are small enough to fit an overhead compartment, but don't really offer good protection if the lady behind you decides to squeeze her backpack in the compartment as well. Enter the Mono Vertigo - I was looking for a gig bag that would fit the bill (decent protection against light weight put on top and an occasional drop from a van), light weight and small footprint. While there a quite a few hardshell bags out there these days (already mentioned the protection racket - really good protection, but heavy and the zippers wouldn't last..), the Mono Vertigo isn't bigger then a regular soft-shell gig bag but the padding seems thicker. The "boot" (rubber padding at the foot of the bag) protects the crucial area in case of most drops. great idea! But here's the best part: as the name implies, the Vertigo opens vertically, so it's easy to pull the bass out while the bag stands against your body. A blessing in crowded jam sessions! There is a neck support that will hold the neck in place when you close the zipper. Genius idea! The only downsides I found are the fact that the bag sits quite high on your shoulders (as most gig bags do unfortunately)..I'm 6 ft 3 and I can't pass a lot of doors or basement ceilings with the Vertigo on my back. But as I said, this is the case with most gig bags. Another is the front pocket: it looks well stylish but in my opinion is a bit too small (and not rectangular) so if you're used to bringing a few pedals and cables as well as a padded strap, you might find yourself running out of space here. This is why I got the Mono Guitar Tick - it straps onto the Vertigo via 3 plastic rings and velcro and stays in place very securely. It offers enough space for a small pedalboard (designed to fit the Pedaltrain Nano) , a tool bag, cables or even an iPad or a Class D amp. So now I can bring everything I need in one go and still have both hands free... plus at the airline check-in you still have only one piece of hand luggage! The Mono Vertigo offers something unique in the crowded market of high-end gig bags: the top-loading design (which I don't want to ever miss again) and the option of combining it with an utility bag, so you can carry most your touring equipment (except your speaker cabinet) on your bag, which makes taking it to your hotel room every night a breeze. Well done, Mono!
