not sure about the bad monkey on that one, the distortion factory i wouldnt use, try to keep more away from modulation and more into eq, mt2 has a good semi-parametric eq that'll get a lot of differant tones, if you want to go balls to the walls, put an eq in the loop and a pedal infront of it
, remember use 0 gain from the pedal, only the level and eq knobs, when you start adding gain from the pedal is when it starts sounding crappy, unless you back the gain off the amp first and then make up with it from the pedal... but it doesnt sound as evil that way
