Who needs wood anyway, I rate my graphite/composite Bogarts over most wooden basses any day of the week... personal taste and all.
But seriously, beyond aging, settling of the fibers etc, a good bass is a good bass. I have played a pre CBS Jazz which sounded and played like a turd, I also played one that made me want to sell a kidney. Same with 2 pre EB Stingrays.
So to me, quality of materials and luthier skills is what makes the bass, not the age.
Just as I would never fork out 10k on a Smith, Thompson, Fodera I would not pay 5k for a vintage instrument. But that’s just me.
And also, so much depends on your touch... tone is in the fingers not the wood nor the EQ.
