I had a really tough time deciding whether this bag would work for my Line6 Pod HD500X and if it was better than the bag available on Amazon. But I finally bought this at a discounted price and and I feel it is pretty decent. YES, it fits the 500x model. I have included a few images here, of the actual bag I got. The padding is good good but I wouldn't exactly call it heavy duty. This is because it does not have a guard and the bottom to prevent accidental bumps when placing it like a suitcase. Zip quality is good and the accessories pocket is quite large, not like it is shown in picture. It has a handle on top and shoulder straps that aren't padded. There is an alternative on amazon considering this fault in the bajaao bag. No side sling as shown in figure. Also the print has only bajaao written on it with its tag line "now go play" without the web address. I don't complain, but it would've been nice if the line6 logo was printed too. I feel bajaao could have made it better, hence the 4 stars.
