Try using the Marshall amp models. You can try using the Mark iic+ model (cali crunch) and throw in a classic distortion at the stomp section with pretty low drive setting, gain and tone past 12 o clock, or you can pretty much do this to any amp to get a nice grit to the tone without getting too fuzzy.
Really there are so many possibilities with the pod that you can try out. Couple of good amp models within the pod: Solo 100(Soldano), Citrus (Orange), Line 6 Big Bottom, Plexi Variac'd, Missisipi Criminal (5150).
