I am still using the stock IRs actually. My setup is from Kingsley tube preamp into two notes cabm into PA, so I am just using the power amp sim and IR. I have used a nux SS-5 before and like the Cabm much better. Before this pedalboard only setup I was using a tube amp (typically a mesa TA15) into a suhr RLIR into the PA and with the new setup, I generally don't miss the amp.
