I'm using ownhammer IRs. They sound massive. Maybe too good sometimes
My go-to IR is a from a Marshall 4x12 with V30s as I'm using the a Marshall 4x12 with V30s in real life.
Ownhammer is my favorite but I always have to level their files as they run way too hot. Very difficult to run side by side test because Ownhammer IRs are so much louder and our ears perceive louder as better
For live, it's a real speaker & cab all the time every time.
