In my experience this is typical of the U1000/Super 70s and Ibanez & Greco guitars. I think they were going for maximum tonal differentiation between the neck & bridge pickups, output level be danged. I have a '74 Greco LP copy where the neck Super 70 measured ~8.6K while the bridge was ~7.4K...
A low-wind set of Maxon Dry pickups (aka Super 58s when used in Ibanez guitars) will put you in the right ballpark too. Same goes for the slightly later FujiGen Gakki Dry 82s found in Greco guitars from '82–86 (or so). FujiGen bought Maxon's pickup division in the spring of '82 but kept making...
That's funky…but if increasing the break angle over the bridge saddles was the goal, it oughta work.
I have a '71 in dark cherry finish. No phase switch. Killer low-wind HB-1s. Only one tailpiece, though. ☺️
Ooh, that's a looker for sure. I've always liked the darker Fender custom reds.
Re. GAD's comment: for whatever reason '70s Tele Thinlines & Customs tend to have really nice necks. Bigger than the '60s slim C but not huge either.
I'm not a fan of the '57s—too mid-pushed for my taste—but a guitar that sounds dark no matter the pickups may be suffering from "pot impedance too low" syndrome. Check out the 525K (or so) pots offered as upgrades by various sellers. IMO they're well worth it.
