Giving props to the movie poster in discussion:
I think this was a COUP for Rickenbacker and it's mass appeal. True, the 4001 (among the many other great models) has it's own attraction without needed the media hype machine to cram it down anyone's throat, but after seeing Fender instruments getting the majority of the exposure in movies and TV, it's great to see a Rick take front and center this time. Not only THEE instrument in the movie, but promo poster placement! That rocks! It would have been interesting to be a fly on the wall during that negotiation. I assume Mr. Hall was present!
On Andy's comment about his initial experience with the 4001 (By the way, welcome to the RRF, Andy!) being a negative one, I have to wonder if part of that encounter with the 4001 tone could be attributed to the amp, and how the tone was dialed in. I know that when I run a Rick 4001/3, and say, a Fender-P through the same amp, I set the tone controls VERY differently for each bass. I fell in love with the 4001 sound and look after hearing Chris Squire for the first time, so that was the model I was shooting for when trying to dial in my tone. Some amps just aren't a good match for the 4001, but CS showed us just how great a match Marshalls and Sunns are! The Fender Bassman is also a nice match on the cleaner side.
I got my first Rick when I was 16 - a 1979 4001 JG. Bought it used for $450 with money I made from my dishwasher job in high school. I still have that bass, although it's gone through a lot of changes over the years. Here's a before & after shot for posterity's sake:
This bass is about to undergo a MAJOR face-lift - will post details as they develop.
