I have a Genz Benz shuttle 6.0-12T combo. I like it a lot, but have been debating a Bergantino HT112 cab. Then I thought, while I'm at it, why not an IP cab? I like the idea of a nice cab and power amp and the ability to try different pres - kind of like a pre/amp/cab system but more consolidated. So, are the IP cabs all they seem to be?
