Thanks a ton guys. Still have to tidy up the power cords and solder 4 more wires. With the Whammy, it's just hooked up via MIDI. I hook up my one 6166 expression pedal to my GCP and set it to CC 11. 0 is heel down and 127 is heel up. With the remote setup like that, you don't have the treadle calibration issues that came sometimes occur. Patches on the Whammy can be changed with different PCs, and you turn it on/off with a CC. I won't be making any Youtube clips of it, but I'll try to get some clips in a few weeks.
Really, the effects portion of the rig is used with all of my amps (5150, EVH 5150 III, Mark III and JCM800). I just hook it up to my loop, and I'm good to go. I have a special cable for changing channels on the EVH 5150 III, hence why I got the RG-16. I never change channels on the 5150, so no MIDI is needed there. The Mark III switches between Rhythm 1 and Lead via the G-Major II. The Recto switches between Orange and Red via the G-Major II as well (G-Major II has a TRS jack, so I can do both via Y-cable). I might eventually bring out the effects only portion into its own rack, but I'm making due with what I have at the moment.
