As a signature feature of G&L, Magnetic Field Design (MFD) pickups are found in the majority of their electric guitars and basses, regarded as a defining characteristic. By transferring the magnetic field to the top of the pickup rather than the middle, they provide a responsive tone with clarity and a wide frequency response. And Leo Fender did this by constructing the MFD pickups utilizing a ceramic bar magnet (installed beneath each coil), with soft iron pole pieces. MFD pickups also yield about twice the output per wind, making them less noisy than most conventional pickups while allowing for greater overall output. The standout feature of MFD pickups is their adjustable pole pieces, enabling players to fine-tune the height of each pole piece for customized string output and EQ experimentation. As a result, the pickups produce less noise, have a very wide dynamic range, and more output while still retainging the glassy tone which we all love.
