The difference between used and vintage seems to be a jagged and thin line over the internet. I wonder how this could be.
Vintage instruments are indeed, in most cases, used.
Not all used instruments are vintage. Just as all cars have wheels, not all things with wheels are cars. Everyone has there own classification of what makes an instrument vintage but some of the lines should be defined by all. An undetermined definition is one that we all face in this industry. I would be grateful to all that have a defined ideal of what vintage truly means.
