- Ray Butts Ful-Fidelity Filter'Tron™ Guitar Pickup -

Some parts of history are so legendary that they never die. The original Filter'Tron, invented by Ray Butts and originally called the "Ful-Fidelity" in his technical journals is one of those things. These pickups are made according to Ray's personal notes, designs and Jones' extensive, multi-decade analysis of original Filter'Tron pickups. Butts was awarded one of the first patents for a hum-canceling guitar pickup (No. 2,892,371, June 30, 1959.)

"This is the real deal...each offering includes all of the original design's bells and whistles...the vintage pole spacing, covers, original zinc-coated backplate used by Gretsch at that time - and more. In Ray's era, factory made guitar pickups were not wax saturated as they are now. These pickups will not be saturated in order to remain absolutely historically correct," said Jones. "I notice a more three-dimensional, open-air quality to the tone of a pickup that is not saturated in wax. Microphonic feedback is not a big issue with this design. To be clear though - I do find waxing necessary for higher-gain, "squeal-less" applications."
