How I go about going for this sound is in guitar rig 4. I can't afford this gear in real life
. I put 2 noise gates at the front of my signal chain then I put a booster (tube screamer). This helps focus the sound and get that start stop effect going. Then, ungodly amounts of gain. Then another gate in between amp and cab. Make sure you mute with your fretting hand as well to make the start and stops clean.
I use the EQ to boost around 3khz.
Hope that helps.
