I've purchased a number of these gig bags, they're a real bargain, I absolutely love them!
SIZE AND FIT
The gig bag will fit electric guitars up to 14.25" (36cm) wide, such as the Telecaster, Stratocaster, Les Paul or similar type guitars; single or double cutaway. I have a PRS and a Brian May Red Special and they fit, as well. Check before you buy, but you should be okay as most solid/semi-hollow body electric guitars are roundabout the same size. Obviously, it won't fit a ES-335 type guitar but it will probably fit a ES-339.
BUILD
The bag is well made from a very thick black leatherette material, which Thomann call Leatherex. It offers very good protection, will take most 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.
