I didn't vote. The way I see it basses are pretty unique, especially Fenders. One 1977 jazz can be drastically different from another. In that sense all of my instruments are irreplaceable.
Now if catastrophe were to strike, I would of course buy new equipment and I am sure I could find suitable basses and amps. They would just all be different from what I have now. Might even be better, who knows, but they would never be 1 for 1 replacements of what I have now.
I don't think I would even approach it that way. I wouldn't be out looking necessarily for a 77 jazz, maybe even not a Fender jazz, nor a Warwick Streamer Stage I, nor the Czech-made SSD I have (that might be somewhat rare to replace).
So since I would not expect a different SSD I found to sound the same anyway, I would instead just look for a suitable bass, be it Spector Euro, Rebob, G&L, Ibanez, whatever would feel good and sound good to me. Ditto for the jazz - maybe a Lakland Skyline, G&L, Fender, or even a Squier. I would be looking for working solutions, not identical replacements.
I would miss my 77 jazz, it's been with me from the beginning, since 1980. But it is just a thing, and playing is more important than what you play on.
