"When Warren Haynes toured with Govуt Mule summer 2010, he used a Custom Audio Electronics rack with a Cesar Diaz Texas Ranger (not pictured) to boost his Firebirds, Klon Centaur, Emma DiscumBOBulator, Boss OC-2 Octaver, and Hughes & Kettner Roto-Sphere (not pictured). He uses a Custom Audio Electronics Super Tremolo (not pictured) as well. On the floor (not pictured) is a Custom Audio Electronics switcher, standard Cry Baby wah (run with 20 feet of cable in and out to eliminate some high end), Ernie Ball Volume pedal, and a midrange boost and bass cut for his Diaz amp. He uses a Planet Waves Chromatic Pedal Stage Tuner."
