I'm not sure really how to explain this technically so please forgive my attempts. Is or was there a reason that most of the records from the 50's and 60's (rock and roll) sound so "tinny" or thin, treble-y, or not very "full"? To my ears when I hear early rock recordings there's a commonality in the sound quality. Is this because the sound "profile" was what was preferred back then, was it a limitation of the equipment of that era, or something else? Does this make sense to anyone? Thanks.
