Very happy with the look of this case, and it is a perfect fit for my 28 year-old RG-550! Very plush inside, love the blue velour. Plenty of secure space inside to store strap, strings, whammy bars etc. etc.
However, I am a little disappointed with overall build quality. The case is actually quite flimsy, not very strong at all. When trying to close the case securely, it takes a lot of fiddling and messing just to try and locate edges together properly all of the way around because the structure is so flimsy. And the TSA catches are not of brilliant quality, again quite flimsy, they don't feel as though they will last too long. I most certainly wouldn't want to put the case with the guitar inside anywhere where even a fairly light object ended up being placed on top, I don't think the case would be strong enough to protect the guitar.
So as a general take home, take to gig/rehearsal in a car, carry in and out, it will be fine if care is taken. However it most certainly isn't a case that I would want to trust to a roadie loading a van!
To summarise, I'm happy with my purchase as I'm not currently gigging but I do wish I'd spent an extra £40 or so and gone for the MR500C, just in case, as it does look as though it would offer far better protection for a gigging musician.
