Chris,
I have no idea who made the infamous PX Special, no label, no brand, no stamp...way back in '79, I think it cost around $80. Built like a tank and sounded alright with rotosounds on it. Basic sunburst finsh, fender-like peg head, huge tuners, weighed a ton. It took a beating and went through a number of looks whilst I was in the midst of my art school days.
I wish there were an interesting story to go along with the Geddy Jazz. Mars Music was running a promotion - re-issue of the his signature model timed with the release of My Favorite Headache. I thought what the hey and entered an on-line contest to win an autographed bass and promptly forgot about it. I thought it was an ugly piece of wood, needless to say the promoter's phone call was well recieved and I've changed my mind, it looks grand. There is only one other like it. I don't play it and my wife won't let me sell it. It's fun to have.
I wish it could be one of those I stood in line for hours at the studio back door and tackled Geddy as he ran to his getaway car..., but nothing of the sort.
Geddy rocks, one of my earliest influences, along with Squire and JPJ.
