I prefer Geddy's Rickenbacker sound to the subsequent ones; the Wal & Steinbergers were OK for the jackets with rolled-up sleeves phase, but I'll take the Ric, thanks.
For me, you can get the Jazz to sound similar to a Ric on certain parts of the neck, but I prefer the colour the Ric paints as you move around the neck. I also don't like the look of a Jazz so much, with its blobby bottom.
Moving Pictures is their best album, IMHO, with Clockwork Angels probably second.
