I really like finding pieces of my chain that I can keep consistent. It helps a lot with option paralysis. So with IRs, I use the Ownhammer 1x12 EVM12L IRs. I go in stereo, with one cab miked with a 57, the other, predictably with a 121. It mirrors my real cabs and therefore helps me craft tones by keeping it consistent between real cabs and IRs. I also find the the EVs pair well with a lot of different amps for what I go for tone wise. From clean to very distorted leads, they handle great.
