OK so first off its pretty darn cool. I nerded out with it for a while but having to copy all the impulses in, rename them to a 3 digit number was a PITA. After going through a bunch of Mesa Cab presets (Celestion V30's) my ears are dead.
I ended up loading the messiah cab to record with and just a quick A/B shows that the Epsi is going to open up a world of sonic torment for me.
I am honestly not looking forward to all the tweaking I am going to have to do. (The power of the epsi compells me)
SO here is a quick sample... 1st part is the Messiah cab impulse on the Epsi. I used the same setup I usually have with the SOD on the Left and the Mesa on the Right channel. Just swapped the cab.
