This time I stuck the HM-2 in front of the JCM800 model on Guitar Rig 4.
Level all the way up. Low around 2 o'clock, high around 4'oclock (right before the point to being TOO honkey, although the honkeyness is kind of part of the HM-2 sound), and the distortion off.
guitar ran through HM-2 and pitch shifted an octave for bass just for more filthiness. Although if I had a real bass it would sound much better.
