Now, I haven't installed the beta yet - I will not have the option until after Easter.
Before I got the AX8 and now AxeIII, I used the Two-Notes Torpedo CAB and the Two-Notes Wall of Sound plugin. Both of which offered the option to move a mic around a speaker. Unfortunately, everything just sounded bad, and it was a real game changer, the first time, I uploaded an Ownhammer IR to my Torpedo CAB. It just worked - even though the Torpedo CAB doesn't support long IRs. It became much better still with AX8 and UltraRes. I recently tried the Mikko plugin as well - there you can also move a mic around. It just doesn't float my boat. If I have an IR I like, but I would like a bit more treble, I pull up an EQ - This is much faster.
I never understood people who did not enjoy long IRs - short IRs are just so flat in comparison - completely without a sense of space and dimension. To each their own - I understand, this is great for people who has experience with and enjoys moving mics around and combining them - Personally, I prefer to let the experts do that, select on of their best mixes and just move on.
