I had the idea of running two amps before, and came across this thread, so it moved me to try it out...

I tried running my valve jr more on the cleaner side along with my vox with more distortion.. AWESOME sound! It ads a whole level of dimension. The dirty crunch combined with the cleaner punchier sound made for a really cool sound, and all kinds of possibilities adjusting volumes of each, and tone and distortion of each. Definitely a cool way to get new sounds.. Also stereo chorus sounds SWEET through the dano cool cat
