Honestly, no.
I bought some for 600 - 800 Euros several years ago, but that was my maximum. I was curious that time, if 1971 Musicmaster Basses would be better than the later ones, but, no, they just were a bit different. I went with Squier Bronco Basses instead. I still have 2 Musicmasters and 2 Bronco basses, but sold the other ones, as they were untouched. The basses I kept are all heavily modified and therefore of no value to "collectors". The current "reverb" prices (>2,000 €) are pretty outrageous for my taste.
