Here's what Lollar say about the Tele Special bridge pickup:
This Special T Series is a higher output version of the Vintage T Series bridge pickup. You get a rounder top end with more midrange and bottom end. Roll the tone control back and you'll get something close to a vintage P-90 humbucker tone. Often paired with our Vintage T or Royal T neck pickups to get more volume boost switching from neck to bridge. Features flat-pole design with graded Alnico 5 magnets, wax potted coils, and vintage style cloth covered lead wire.
