Observation of the guitar-playing community (that is, innumerable players over the decades, not individual comparisons) would surely suggest that the broad tendency is for more massive guitars to create/be used for thicker sounding tones, and lightweights for more trebly stuff. This is surely influenced in part by players choosing instruments by custom (LP = heavy sustain) rather than by year, but surely, too, there are reasons for these stereotypes. On the other hand, my experience has been that it is generally not only possible, but now quite easy, to get really heavy sounds from a Tele, and unless the pickups are too hot, as many are, it's possible to get really cutting and airy tones from a LP, so I think of the generalizations as tendencies, and not absolutes or limiting factors. The acoustic tone of an instrument definitely features in its amplified sound because the body of the guitar contributes to the way the string vibrates. But here, too, it's a matter of degree -- not a be-all/end-all factor, IMO. A lot of this stuff can be trumped massive by a simple knob tweak on the amp, or the use of a pedal. I tend to like any guitar that plays well and has good (= non overpowering) pickups. I almost never feel limited by any good, functional guitar. They can all do so much!
