I've been trying out the new Redwirez Bogner 2x12 IRs with my Dćmoness 7, which now has a BKP Aftermath in the bridge position. This IR set seems to give a real grindy, heavy kinda Whitechapel style tone. I used the SM57, cap 0.5" impulse for the main part of the tone, and I also blended in a little bit of the Redwirez Uberkab IR too, using the T75 speaker and SM57.
Good lord, that's heavy. Me likey!
