I'd probably use my 70' P if I was doing a lot of early Rush. Pretty much nails that tone with the Harris sig Duncans. Like a few others here, I'm not too keen on my Jazz. It's a Squier VM '77. Love the way it plays, hate the tone. Maybe time for pickups.
I like Fender Custom Shop 60s Jazz Pickups and a series/ parallel mod to fatten a Jazz up.
