I really like the design thinking behnd the TC stuff, but I can sort of see why it hasn't caught on. You do get a really sleek package, and more flexibility than with an ordinary combo. On the other hand, you are stuck with the two or three heads that actually fit, and if something should go wrong, there is a possibility that you might not be able to replace the head with a model that fits, and be left with a cab with a great big hole in it. The problem is, I think that this kind of solution appeals to combo buyers, but not to head/cab buyers, and at that price point the head/cab buyers are the ones you need to appeal to.
