check out the Two Notes Wall of Sound IR loader plug in
http://www.two-notes.com/en/software/torpedo-wall-of-sound-3/
allows for power amp on/off (can be used with POD full or Pre amps) with power amp tube choices/eq functions
a variety of proprietary cab IR's or load 3rd party IRs
a variety of mics and allows mic placement positional changes
post cab eq functions, stacking of cabs etc etc
Its free to try for 30 days
Once you get familiar with the interface its easy to use
Ive been using it for the last week or so, and to me its made a huge difference to my HD500X
there is also a Torpedo CAB pedal for live use with much the same funtionality
not spruikin, just saying,
might help someone out
cheers
