I agree Ian, the vinyl version is much different to the CD version I have. The rhythm guitars are much lower in the mix it seems. Honestly I don't know much about the vinyl process so I can't comment too deeply on it.
I did some reading last night, and the general interweb reckons that his vocal was pretty much always doubled, with one of the doubles slightly down or up tuned and panning them a little. I can definitely hear the doubling on just about every song on the album, but not so sure about the de-tuning thing. I've tried something similar in the past and it was way more phasey/chorusey than Sab. Maybe they just did it better than me though
