Guitar shops selling new basses and guitars are going out of business every week.
There was always the moan in the trade that the internet trade was killing the shops.
Since I’ve stopped working in a guitar shop, I’ve not bought a factory fresh/shop fresh bass - that’s 6 years. And I’ve bought and sold about 20 basses.
Market saturation?
There are also folk who have ridiculous collections.
I’d suggest @cetera has about 40% of all basses ever made.
