I bought this bag for my Line 6 Helix processor. The Helix fits perfectly in the bag and it is able to cope with the Helix's weight without any problems (the Helix is pretty heavy, being all metal).
Something that I don't like much is that it cannot stand upright, no matter how I put the Helix in it - it always falls on it's side. But I guess this is acceptable - just have to know that this happens.
All in all, I am happy that I bought this bag.
The order processing was a little bit problematic this time and I had to call the support to check about the order but the lady was very helpful and the problem was solved quickly :)
