I know this comes up from time to time...I'm 47 (which makes me 'vintage' I suppose) so my perspective is that anything older than 30 years old guitar wise is considered vintage. Some say 25 years... I have a couple of guitars made in the 1980's, but its hard for me to label them as 'vintage'. The guitar I've had the longest, a 1992 Japanese Fender Stratocaster (1954 RI) is considered 'vintage' in some circles. I say 30 years is cutoff - what say you?
