Purpose is to be able to select G-Major program with selected TriAxis program, while also being able to select any of the 18 pedals. (EDIT: There are two sets of pedals in series, which make the 18 pedals look like 16 pedals)
BTW - Input is one channel of the ISP Decimeter and then into various boost/overdrive/distortion type pedals (Controlled by GCX #1) directly into input of the TriAxis preamp, with one dry signal into one channel (Left) of the Rane 26S mixer and then into the second set of echo/flange/tremelo pedals on the second GCX then into the G-Major 2 feeding into one channel (Right) into another channel of the Rane 26S mixer, then into the second channel of the ISP Decimeter and finally into the 2:90 amp (Which feeds 2 Mesa cabinets).
Wiring sequence & schematic would be appreciated as will programing information.
