Geddy did it with his Jazz. I think your starting point is Rotosound strings.
I don't think Geddy's Jazz sound has ever been close to his Rick tone, it's very different. And Rotosounds aren't that important, maybe back then they were but these days there are so many roundwounds available, many a much better quality that Rotosounds too. Any fresh set of bright aggressive SS rounds should so the trick - I've used DR Hi Beams for years for these types of tone.
