The way I hook it up is about like this – run through the distortion/preamp first, then split the signal and send one to the Eclipse, and one to the Gmajor. Then send the stereo outputs of both units to a line mixer for further level balancing and routing (two guitar amps in garage-band situation, or separate channels on the PA's mixer).
So you could end up with 5 channels going to the board for 1 guitar rig – amp mike (preferably dry), Eclipse L/R, Gmajor L/R. Get a dedicated guy to ride those 5 faders for you at FOH and people will fall at your feet.
