I'm one of the folk loving their new Genzler BA12-3 cab... I'm feeling the need for a cover for it as I schlep it around. So, I'm wondering whether other early adopters of this cab have purchased covers and if so from whom and how do you like it? I know that the major companies all will make custom sizes and that ideed, all of the covers start out as custom ones... I'm just not sure how I trust my measuring skills so I'd like to not be the first one that company has made.
