This phenomenon is well-known among Fender Stratocasters. The guitars which have been played for years (e.g., a country musician played it every night for 20 years) are distinctly different (feel different, play different, sound different). I would never believe it myself had I not personally experienced it many times. Explanations are completely lacking, so it's just a strange phenomenon but there's no dispute about its existence among pro players.
