this is a 5 watt (1 6v6), 29 lbd 1x12 combo. it has another new badcat product called the "unleash" built in. the unleash is basically a reverse attenuator. to activate this option, you need to connect an external cabinet, but once you do, there is a control on the amp called "unleash" that allows you to dial anywhere up to 100 watts. it sounds amazing, and retains a nice gain (if you want it) even at the max wattages. very warm sounding. This was the best thing i saw at namm this year. it sounds really sweet at 5 watts too. i spoke to the guys at the booth, and they said matt's music will be getting them. they sell the unleash seperately also, so you can turn any low wattage amp into a giggable moster.
