Axe-fx -> Yam DSR115. For high gain, I have been struggling to get at least some semblance of an "in the room" 4x12 sound. Went through a million IRs and no matter what, the sound isn't "right there". The highs always sound weird to me, and the midrange seems off in the distance. It doesn't sound "direct" enough. After thinking about the word "direct", the light bulb came on. Let's inject some direct in to the mix. So I paralleled a PEQ with the cab block, put 1 @ 200Hz blocking, 5 @ 3.5KHz blocking and... BAM!!!, instant in the room 4x12!!! The mids are in your face as they should be, the highs sound right, and I even get that guttural thump like a real 4x12! I have barely scratched the surface as the possibilities are endless with the mix ratios, playing with the 3 other bands in the PEQ, etc. Awesome!!!
