I like microphones as well as basses. The value of practically anything old that was originally a professional tool (rather than domestic, but then some of them go for stupid money too) has been rocketing for years. AkgD19 for example - used to be cheap as chips in the 90’s, but now it’s “the Beatles” mic and sells for 300 squids. Daft.
Most home recording marketing depts are selling with the nostalgia theme.
I agree that people priced out of the 60’s era basses are now going for 70’s, whereas 20 years ago, 70’s instruments were considered sub-par.
”They don’t make them like they used to!”
(it’s still a lovely bass though)
