Yep, a Dr. Z amp. They are simple and pure handbuilt tube amps. Awesome clean sounds and a nice smooth breakup when you push them. Most of them are pretty low wattage, so you get alot of response at mid level volume..not like a 100 watt Marshall or anything. They are a pretty good value for what they are, too. I've played a Maz18 and a Perscription in the line, too, and they were great amps as well.
I know Brad Paisley is a huge DrZ supporter and user, too. He;'s a monster picker.
