Tom Sawyer Lead by Andy Skuse
Pretty basic Mini Moog lead sound. Getting the tuning of Osc 2 just slightly a hair detuned will help fatten up the sound and create the modulation and movement that you can hear in the original recording. With the modulation settings as they are you should be able to push up the Mod wheel at the end of the repeating pattern just as the guitar solo gets started and get that out of control mod sound. Also, Geddy used Glide a lot for his Mini Moog lead sections, so set Glide to 6 and you should be right in the ballpark. Enjoy!
