If you're taking issue only with recording technology, you might have a point, but you're clearly not, because you're talking about guitar pickups. I get that you don't like Hilotrons, and plenty of people don't. However, if there's no great recorded guitar tones prior to 68/69, why are so many big name amps currently in production (Fender and Mesa Boogie just for starters), based on, and trying to reproduce sounds of that era? The same applies to guitar makers, and pickup makers. The reason is that those old amps and guitars were NOT hi-fi. If guitarists wanted hi-fi, they'd all be playing through solid-state amps or more to the point, would be going directly into the PA.
