At the moment, I'm sitting about 30 miles away from my record collection, so I can't give you specific instructons. But I can give you some general tips on how to dial-in a sound.

Start out clean. Get as close to your target sound without effects as possible. Then add in just enough distortion. Then add in any short-timeframe effects like flanging or phasing. Save reverb, slap-back, or chorusing for the last.

Trying to get it all at once can be just too frustrating to handle, but if you crack it a bit at a time, you can usually find what you're looking for.

Good luck!
