If that's the same one I've got (well, I have the 8" version, not the 10" version) it has a three-position attenuator control that'll knock it all the way down to 1/4 watt (1/10 watt on the 8" version). It's pretty cool for getting some cranked up dirt without waking up an infant.Yep. It's a 4.
Nice!
Is that the AC4TV?
