T-Rex Room-Mate Tube Reverb - Jimmy is playing a American Fender Stratocaster through a Matchless DC-30 set on medium grit settings to see how the reverb handles grittier tones. Three microphones were used on the recording (Shure SM57 and Fathead II-SP Ribbon close mic'd and Shure SM81 as room mic). SM57 and Fathead used a ART Pro MPAII PreAmp, all three channels were mixed and fed to M-Audio Firewire 1814 interface.
The T-Rex Room-Mate is a tube driven (12AX7) reverb with 4 modes of reverb.
