ROG Condor Cabsim seems to be the most common cab sim out there. I know Thomas at THCustoms sells boards for it and also a board for a headphone amp. He also has all sorts of all in one home recording stuff. There are a few other layouts for vero cabsims out there. I know the Marshall cab sim is out there some where, I saw a layout for something on DIYStompboxes. There was a guy on the Madbean forum working on an all in one headphone amp/recording to FOH out, but that was before the recent crash. Sorry I cannot be more helpful.
MAO Pedals has a layout for the JamMix headphone amp on the forum,
