I think the issue is that it doesn't come with the BB802. The BB800 bag I would imagine will continue with the old bag.
Having said that 37 euros doesn't sound too bad.
Ah right. So the v2 bag is not the free one with the BB800. Thanks for clarifying that.
Personally I use a med size camera bag to hold everything other than my bass and cab, my current head is a GK MB800 so nice and small.
Price wise I think the Quilter bag is less of a rip off compared to the likes of Markbass and even TC Electronics.
