There was a time when I sneered at gig bags, and would only get hard cases for my guitars and basses. My attitude has since turned around on this opinion, and most of my instruments are in gig bags now.
I would feel differently if I was playing out a lot and had to stick my gear in a van with the rest of the band’s crap, but that is not my situation. For around the house or loading up my car a gig bag is plenty for me. You will find that lightweight and less space are big bonuses, especially if you are using public transportation.
For starters, this is a double bag so it holds two solid-body electric guitars, which makes for a tidy package when travelling, and it is always nice to have a spare guitar at a gig. It fits most of my electrics, including the Strat, Tele, Les Paul, SG, and even a pointy headstock metal thing. Of course my Gibson Explorer will not fit, but I never through for a second that it would, and Flying Vs are probably out of the equation too.
In case you are wondering it is around 42 inches long, and will fit guitars with a 12 inch upper bout and a 14 inch lower bout. More or less. And the whole thing weighs in around 7 pounds, without any guitars in it. That is pretty heavy, but fortunately it has comfy built-in backpack straps that tuck neatly out of the way if you are not using them.
Those guitars are very well protected inside, thanks to generous padding and a super-nice neck support system that might be able to keep you from snapping your Les Paul headstock off. It has a heavy-duty nylon exterior that is pretty much water-resistant, and the dual zippers are as heavy as they come. There are plenty of pockets, and they are well padded to keep the contents safe, as well as keeping whatever is in them from damaging your guitars.
Ergonomically the MONO 80 is awesome, as it Is very well through out, and it even balances well on the carry handle. This is the nicest gig bag I have ever used, but it is not terribly cheap. One of these will set you back $329 ($415 list), though that does include the MONO limited lifetime warranty. For that price, I cannot imagine them hassling you too much if you have to file a claim.
Check one out for yourself and see what you think, I think you will be impressed!
