well, I've always dismissed seventies Fenders as just horrible, and the ones I've played have generally borne this out. They've been heavy, dull sounding, ugly. The contouring (or lack of) on Strat bodies is frankly hilarious! Then, yesterday, we were trying out a 1968 Vox AC30 that my friend is working on, and the guitars near to hand were a pair of 1977 sunburst strats, one trem and one hardtail. Oh dear! they both sounded great! and the hardtail in particular played beautifully. Thinking "it must be the amp", which does sound amazing, we went and played them through a Marshall DSL combo. Same again. The hardtail in particular sounded really good. we then compared it to a brand new American Deluxe Strat, which sounded thin and sterile in comparison. The shop has half a dozen other seventies Fenders, and the other two I tried were as expected, heavy and dead sounding and played like cheap rubbish.
I now find myself in the horrible position of wanting something I've always sneered at before :)
