I've purchased two of these acoustic gig bags and I also have a number of the electric guitar type for my other collection of guitars; they're a real bargain, I absolutely love them!
SIZE AND FIT
My largest acoustic is a Takamine GJ72CE-12NAT, 12 string, and it's a bit of a chunky monkey; it's a big beast! It has a 17" jumbo body but this gig bag can take it. I would say that's about the biggest acoustic guitar the gig bag will take, you will really struggle with anything bigger than a 17" jumbo body. The specification of the Takamine GJ72CE-12NAT is: lower bout width, 43.5cm (17"); lower bout depth, 12.5cm (5"); upper bout width, 32cm (12.5"); upper bout depth: 10.5cm (4"). The length is 20.75" (53cm). Other standard body types, such as the 16", Takamine NEX, grand auditorium or dreadnought, will easily fit with no problems.
BUILD
They are well made from a very thick black leatherette material that will take the knocks, it's waterproof and it's easy to clean. The pockets are made from the same black leatherette, complemented with a thick woven material, which is in a really nice medium brown colour with matching piping; it's not pink like in the photos! Your guitar is very well protected as well because of the 30mm high-density padding, which is of a good quality, and there's a plastic protection strip at the bottom of the bag to absorb any bumps.
There's plenty of storage for your bits and pieces. The back-straps are great and can be hidden away underneath a pair a zippers. This is a really nice feature as the straps then don't flap about and snag things, but are very easy to get at when needed. It also has a long single shoulder strap, a handle and even comes with a d-buckle on the back, near the top, so you can hang it up, what more do you need! If you're feeling up to it, you could actually carry three guitars into a gig; one of these on your back and two others in either hand!
Overall, it's a fantastic gig bag, I just can't fault it. The bag looks very classy, it's robust, it will last for years and you won't find a better gig bag for the price. I spent a lot of time looking on-line before I bought one and nothing out there could beat it.
Highly recommended.
