Neat.

OK. So I first I have to put out there that my Sweetwater engineer warned me about this thing. He mentioned that it was a pretty rowdy rig. Oh boy, was that an understatement. So I plug in my LP Traditional and hit an open A cord. I am still grinning several hours later. I couldn't make this thing sound bad. When I brought the bass up past noon it felt just like standing in front of a kick drum. Tight and focused and huge. So it does the LP thing. I decided to plug in my Tele and see what happened there. The neck pickup sounded like a warm safe place that if I was a child that I....Wait a minute. It was the sound of heaven. Warm and buttery smooth. I didn't even try the bridge pick up. Why would you with what was coming out of the neck? By the way, this amp really likes loud. And it doesn't seem to do pristine cleans. Shirley is dirty and that's how she rolls.
