Here's an email from Geezer about the basses he used in the 70's:

I used Laney amps and Laney cabinets [mainly 4x12] in the early 70's; I gradually switched to various pre-amps going through Crown power amps and custom built JBL speaker cabinets. I started off with a Fender Precision bass, but was forced to switch to a Dan Armstrong plexiglass bass when someone in Canadian customs chopped up my Fender [its a long story]. After that, i had custom made John Birch and Jaydee basses, and occasional Rickenbackers.
