My rig is simple these days. We used to have all these amps and pedals and effects. We had this giant rack with all kinds of stuff in there. Now with the new technology, ever since we switched to the Kemper Amps preamp, it has all the sounds, guitar tones, effects and everything in one. It’s an amazing unit. It has all the noise gates and effects you could imagine: chorus, reverb, delay. It’s just this three-rack space unit that has everything, when we used to have 24 racks or 36 racks. You don’t have to go big anymore. It’s very convenient and light. We can save our favorite amps now. They never leave the house, and they never go on the road anymore.
