I use a buffer after the guitar pedal board...pumps the signal up so you can run a good solid level 1/2 a mile...run that channel down one of the TRS return to the tracking room, then convert signal back to regular old 1/4 cable, into the amp(s)...

Hi gain things and single coil pickups (strat, tele, et al) will buzz like a big dog if the player gets too close to the video monitors, though...
