Hey MJMP, it took awhile and countless signal routings I think I wired it every way possible, but here is what I decided on:
Floor Board-
Guitar>Noise Suppressor in. Noise suppressor send>Tube Screamer>Super OD>GE7>Noise Suppressor return. Noise Suppressor out>Morley A/B/C in. (Morley a/b/c) A>GE7>JMP1 in, B>ADA MP1 in, C>Morley A/B in. (Morley a/b) A> Rack Tuner>Piranha in, B>voodoo Valve in. Ground Control Pro wired to all 4 preamps, G Major2 and Intellifex. I use the CC on the GCP to turn on/off G Major 2 effects.
Rack-
ADA MP1 r/l out>r/l in BBE 462> channel 2 on alesis mixer
JMP1 r/l out> r/l in channel 4 on alesis mixer
Voodu Valve r/l out> r/l in channel 6 on alesis mixer
Piranha r/l out> r/l in channel 8 on alesis mixer.
Intellifex in fx loop of Piranha
Alesis Mixer out > G Major 2 > Carvin Power Amp > 2 ADA Split Stacks.
Very versatile set -up. I can use any combo of preamps, from 1 to all (not that I would use all at once) but you could.
