I ordered this with fingers crossed, as I wanted snug-fitting protection for a steel-string parlour guitar rather than a 3/4 classical, and the accuracy of measurements for guitars and cases on websites isn't always reliable.
I needn't have worried - the gigbag is indeed a pretty snug fit for my guitar. It's also pleasantly surprising in terms of its sturdiness and versatility. The overall quality of finish and the depth and firmness of padding is more than might be expected at this price point, and the two pockets provide plenty of handy storage space for both music and accessories.
Overall, then, very warmly recommended; as a bonus, the service from Thomann was exemplary.
