I only have experience with my 1970. That neck is ridiculously thin and flat. There is no other neck ive played thats similar. Later years got baseball thick. It also has the original 6 pole toaster pickup and later 70's 4 pole bridge pickup. With new rotos, through a good rig, the bass is a knife thru butter. Warm but cutting, twangy yet has great bottom. All the bad design foibles dont really seem to bother me when I'm railing "Free Will" or "Xanadu". I recently had the frets leveled and recrowned and the bass plays better now than it ever has, at 55 years old. Original Grovers died in the 80's, but were easily replaced. Now it's with a good friend, who also prizes it. We trade it back and forth every few years. My most used instruments now are my Streamer and my Sadowsky Modern, neither of which are very similar to the 4001. But it has a uniqueness no other brand has, and IMHO they're beautiful too.
This is the only pic I could find. The binding has turned yellow over the decades. All the other basses in this pic have moved onto new owners.
