Chris mentions early in this video (at 1.19) that he switches amps via Bob Bradshaws (Custom Audio Electronics) 4 X 4 and RS-10 Midi Foot Controller. At 3.13 in the video he again mentions the 4 X 4 - "It's just 4 loop and 4 on/off switches". Again at 5.06 Chris mentions his 2nd 4 X 4 - "I have another 4 X 4, because I use all the channels. I have 8 loops and 8 on/off switches. It works out great, there is no latency and the tones are really pure. It sounds good."
