One thing does come to mind, although it's pretty obvious. Have you tried swapping the left and right inputs to your amplifier? It may be nothing to do with the empeg at all.

Yep. Using the (working) right channels being output from the sled, I plugged each into each of the amp inputs, and got clean audio through each. Repeating the experiment with each of the left channels rewarded me with nothing but silence. The same happened when I was inside, using the RCA inputs on my stereo. Right == music, left == silence.
