The first album he is used the jazz on was Moving Pictures. Limelight was all jazz, but Tom Sawyer, Red Barchetta, etc. were Ricks. He bought those used 72-74 Jazzes used a few years after thad had been made. He did own the Jazzes for a while before really settling on them later, that is why Limelight stands out as being unique for that period. Now Geddy was using an old P-bass before Rush and for years afterwards. You can hear it on By-Tor and the Snowdog (the growling sounds) and on their live album All the World's a Stage. He later shaved the body, painted it like a blueburst, added a treble pickup, and rewired it run in stereo. Yes he had been using fender sporadically throughout the early years. He used the Stein not very much in the studio. He used it(them) live more than in the studio to allow him to move more easily among the keyboards. He recorded a lot of songs with the Ricks and Wals, but toured with the Steinberger. So that can be confusing. I wish I could find those old articles where he explained a lot of this.
