A couple of things not covered, and not concerning electronics related, are that the older basses generally had a thicker, Gibson-like neck. I much prefer the thinner necks of the newer models. The old ones have a thicker body and weigh a bit more - I love that part! The necks are set back on the body about an inch, so they are a touch less neck heavy (Get a Balance K, if you want perfect balance). The bridges are not as adjustable as the newer ones. The newer ones are wider (deeper) in the dimension of the saddle area, so greater adjustment is possible on newer models. I believe an 80 would have the double truss rods, something I consider of great importance. If you slap, the pickup selector can be a bit painful, if you don't watch out on the old ones. This info is just posted for FYI. IMO, the old ones and the new ones are almost equal when the variable of woods aged another 20+ years is put the mix. Now if you can get a new one made of aged (20 years or more) woods, that would be great! Bob is on the right track.
