Fishing here a bit, but I have a Wizzy 10 that I quite like, but I've been thinking about a 4 ohm Wizzy 12 cabinet, because I also have a combo with that speaker and it would make a proper extension if the cab matched. The 10 is great for almost any jazz gig and it does work as an extension, but doesn't seem to add much. I hear that 2x12 is a deeply moving experience. The 12" cabinet is 11 lbs heavier than the 10, which is why I love it, but having all of my gear play nicely with each other is a good idea too and might be worth a little extra weight. I have a line on a fairly priced used one and if it pans out, I'll buy it and then may decide to sell the 10, but I thought I would fish for someone who has a 12 and wishes it was lighter. PM me if you're interested.
