I bought this bag for my Recording King lap steel guitar, which is quite a bit wider than some other lap steels but which is, of course, a lot shorter than a 'normal' electric guitar. This isn't a lot of choice available regarding this size of gigbag, and I narrowed my options down to this Thomann bag and Fender's Urban Shorty Strat bag. The Thomann bag costs less than 17 Euro, while the Fender bag costs 30 Euro. The Fender definitely looks the nicer bag, but as I am more concerned with value-for-money than aesthetics (at least when it comes to guitar bags), I opted for the Thomann bag.
The bag is actually slightly too big for my lap steel - which is approximately 3 cm narrower and 5 cm shorter than the Thomann bag (the internal dimensions of which are stated as being 88 x 24 x 6 cm). However, the ample size of the bag is not a problem, particularly since I added some additional padding (consisting of some rolled-up bubble wrap wrapped inside an old [clean] sock which I taped to the inside of the bag with gaffa tape) to make the lap steel a very cosy fit inside the bag.
The bag appears to be well-made from a 'tear and water-resistant' material. The zips work smoothly and the shoulder straps fit me perfectly once they are extended to near their maximum length. The 10 mm foam padding is adequate. The Fender bag has 11 mm padding but I doubt whether the difference would be noticeable. I agree with some other commentators regarding Thomann gigbags that the zip on the outer pocket should be positioned differently (at the top of the pocket rather than on its side) but that is only a small quibble.
In conclusion, I have no hesitation in recommending this item as a good value and good quality bag for mini guitars and lap steels.
