I find it's always the same guys profiles, M. Weinstorers S.Mehle modded amps ( including the bassman )from Rig pack 1 & 2 are still #1 in my book.
Fastredponycars Nitro profiles.
Mats Nermaks Two rock and black goop(Dumble).
Oh and and another hand up for the Morgan AC20, Okstrats profiles are worth exploring, cant remeber the names.
I have always been interested in the commercial rigs but have yet to purchase any, not because I'm cheap, but never felt the need yet in the 10 months I have owned it.
Don't forget to tweak, i find the cab parameters a good place to start.
Enjoy.
