Hey Bernie,

Some other RealBand Audio Effects you could try playing around with are the Compressor and the Exciter. There is also a Vinyl effect you can access by going to Audio Effects > DirectX Audio Plugins, and selecting PG Vinyl Tool. That could help you get a nice raw sound.

If those don't get it to where you want it, I'd recommend trying out some third-party plugins. There are plenty of distortion VST plugins out there, and one of them is sure to be able to capture the tone you're going for.
