Here's what Lollar say about the Tele '52 bridge pickup:
Wound to 1952 Telecaster pickup specs, the '52 bridge model gives you a clear and bright Tele tone with a distinct round bottom end when played with a soft attack. It produces a full, fat rock tone when used with an AC 30 or Fender tweed amp, and the definition holds together nicely with heavier amp distortion. Features a flat-pole design with Alnico 2 magnets, wax potted coils, and vintage style cloth covered lead wire.
