Isaac Brock's rig or something close to it...

Hey. I am looking to build myself a new rig but I am not looking to spend a fortune on it. My current rig can create similar tones but they tend to sound cheesy and fake. I greatly admire the raw sound Isaac has in his old and new albums but have little knowledge on how to get a similar sound to it without burning a hole in my pocket. Any suggestions?
