Taken from Lollar website:
“With excellent note clarity for a humbucker, we often describe the dynamics of the El Rayo® as having a percussive quality almost like a single-coil pickup. The entire frequency response is relatively flat, with increased note bloom and less compression than a typical P.A.F.-style humbucker. Read more about F-spacing HERE. El Rayo F-spaced pickups are available in a wide range of color options and wiring is 4-conductor only.”
