I'm never buying a gig bag again
This case is PERFECT - the best of both worlds. It has the durability and toughness of a hard shell case and the portability and light weight of a gig bag. It fits my PRS Custom 24 very snugly, and it doesn't move around AT ALL inside the case - super secure. I was pleasantly surprised to find that this case fit my PRS, since PRS guitars aren't exactly one of the standard "Strat / Tele / Les Paul" type-shapes. At first, it seemed like it wouldn't fit - the case seemed just a bit too small to accomodate the end-pin at the bottom. But the dense foam that lines the inside of the case actually re-forms around your guitar, so now the foam is perfectly molded to hold my guitar! Awesome.
So how tough is it? It can pretty much handle everything a hard shell case can, without breaking your back. I wouldn't put this thing on an airplane, but it would definitely take being jostled around in a car / train / bus / etc. It uses the same dense foam that SKB uses in their hard shell cases, so you know it can withstand a lot of punishment!
It comes with a front-top pocket which I use to store my guitar strap, another front pocket that I use for cables, and an inside compartment to store other stuff. Since the fit is so tight, you won't be able to keep your guitar strap attached to your guitar in the case though, but that's what the front pocket is for.
And, the kicker for me is that it comes with backpack straps! Let's face it, most of the reason why we buy gig bags is because they're cheap and portable - we can wear them on our backs, and they're not heavy. But they're all very fragile, and don't do a very good job of protecting guitars. For instance, would you feel comfortable if your gig bag tipped over and hit the floor? Probably not too awesome. If this thing hits the floor, nothing happens. Your guitar is perfectly safe. Yet it's just as portable as a gig bag, and not much more expensive. Next time you find yourself considering a gig bag, you should do yourself a favor and get yourself one of these fantastic cases instead - you definitely won't regret it.
