Yeah, stores shouldn't screw things up like that. If I called a store and asked them to order a mk IV long head version because I wanted to buy it, then i'd have to put some money down, and when I get it, i'll be sure to find that the long head looks like sh!t on a 4x12 cabinet because it's really a medium sized head and isn't the same size as a recto. I'd be really cheesed off, but of course this is an extreme scenario but still..they're the professionals, ( i'd like to think ) they shouldn't have the amp heads formats messed up.
