I liked your Mesa V30 #1 clip. I bought the 412-GTR Mesa V30 #1 and 412-GTR SLM M75 cabs. I have to say that initially I thought the cabs were tubby or thin compared to my Uberkab Redwirez V30 mix but I'm making progress.
IMO that Diezel IR isn't even near OwnHammer quality. It's not balanced at all. I'm sure you can get okay tones with it but it will be a lot harder than with OwnHammer. At least I had big problems with the low end of that cabinet. I would have to go back to cutting the low end with Global EQ.
