First off, I LOVE the Clean Red channel.
I dialed in a very nice clean sound with it and then added a touch of sine chorus. I was fairly happy with it, but last night I got to actually looking inside of all the parameters in the display screen, and I went, "hmmm... I wonder what setting this effect to Post instead of Pre will do?"
WHOA.... it lept from the amp and bathed the whole room. I almost swooned a little.
I recommend that everyone try to run your modulation effects Post, if you havent allready.
It made a huge difference to me.
