For anyone who's interested,  here's a blanket setlist created for the DT50 and HD500 that tests each amp model.  This was created with the help of NickMattocks and bbenham.  I just took thier lists and tweaked them to be a "cleaner" starting block.  So thanks guys...

Each patch uses ONLY PRE amp models

Each patch includes NO EFFECTS.

Each patch includes NO Cab sims.

Each patch is volume normalized to the setlist, and a clean guitar signal(no amp)

Setlist includes four patches from each modeled amp.   Each amp has a patch 1-4, with 1 being the cleanest drive (0%), 2 (33%), 3 (66%), and 4 at 100%.   All patch volume levels were normalized using a meter in the room(to the best I could do).  If the amps cleanest setting did not produce enough volume to normalize via "channel volume", then the volume was raised in the mixer.  If the mixer still wasn't enough to bring volume up, then drive was increased just enough to normalize for the #1 patch.

Hope this is helpful...

EDIT:

Forgot to mention... All panning in the mixer is set to "Center" as well.
