We all have our own reasons for playing vintage basses. I bought my first in 1979 and have usually looked to buy them when I wanted a new bass. It’s alway been my default purchase.
As I have possibly said previously, in my opinion the comfortable, worn-in feel of a 60 year old nitro finish neck cannot be surpassed, so the playing experience of a vintage bass has a head start. I have had a number of more modern AVRIs, custom shops, JV Squiers and although they are very good, they are not the ones I reach for when I am searching for Musical inspiration. In fact, I almost never reach for them, when I want the best possible bass.
In my opinion, asserting that other people you have never met own vintage instruments as a status symbol or are part of a cult, are “bonkers”, or buy to prevent others from buying is an interesting point of view.
But it isn’t a view that reflects me, or as far as I can tell, the people I have met that play vintage kit, many having owned them since before they were of significant value.
