I would look into the blackface models on there, and depending on the response of you headphones the tweaking of the EQ may vary a little, but I would approach it like a real fender twin rig, low bass, 1/2 way with mids and high treble to start. mix in some gain, maybe a OD pedal set low and level to add harmonics and some tube crunch. If it is anything like the other modeling out there that should get you close... I found a Vox "bright" model with some crunch one time to be really nice for some older Jerry tone. Maybe that could help, maybe not. Good luck.
