That is what I always struggle with about vintage.. those instruments are so heavily sought after, while in general, you would call them by today's standards faulty units or design errors. sure they are collectible for historical reasons, but claiming them to be superior, while knowing how experimental they have been, is just wrong, IMHO of course
Sorry, don't want to derail the thread with that.
When people like the sound of something, it's like they don't even care if it was properly beta tested, peer reviewed, FDA approved...
Most people are still listening to old instruments on new records, as well as old records. Great players still use them. They didn't suddenly start sounding bad.
