I stayed up just 'cause you said you were close to posting this and I wanted to hear it before I knocked off for the night.
Was not disappointed.
Edit: Try the bias trem on the AMP block.
From what i read, Clapton specifically requested the bias trem to be added to the Champ, and wanted the effect to be subtle.....and it is, nicely so, IMHO
I was so impressed with it I just had to belt out a blues jam and write a preset. So, here it is...
