Ray Butts Ful-Fidelity Filter'Tron Neck

  • Ray Butts Ful-Fidelity Filter’Tron - Neck - Pro Gretsch Mount

    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.”

  • Cover Options:

  • Blank Cover - Late 1957-1958

  • PAT. APPLIED FOR - 1959 - Early 1960

  • U.S. PAT 2892371 - 1960 and onward


    Tighter bass response and slightly more top end EQ than a TV Classic. Truly unique sparkle and dynamics provided by the lower output and absence of wax. If you want the that unmistakable Great Gretsch Sound then these pickups are the way to go.


    The Pro Gretsch Mount is a direct drop-in replacement for original sized Filter'Trons - with the vintage “tabs”. This pickup comes with two pieces of compression rubber and 2 mounting (wood) screws. Please refer to the Tech Specs tab to learn more.

  • Output/Power

    DC Resistance is not entirely an indicator of true pickup output, although it can be helpful.

    Bridge: DCR - 4.2k

    Neck: DCR - 3.8k

    "We offer a lower 3.8K ohm version for the neck position, and a 4.2K ohm version for the bridge position. I have worked on many late ‘50’s Gretsch guitars with these ohm reading variations...most vintage Filter'trons float somewhere around 4.0k" - TV Jones.

    Wiring Notes

    This pickup is shipped with vintage spec 2-conductor wire.

    Helpful Notes

    Gretsch Electromatics and Streamliners: Out of respect to Ray Butts family and authentic design, we only offer this pickup in the Pro Gretsch Mount - the way it was originally made. This pickup does not fit in Electromatics, Streamliners, or any other guitars that suspend mount pickups. If there is a will there is a way, but it would take considerable modification to the instrument and pickup to do so.

    Filter'tron Replacement: The Pro Gretsch Mount is a direct drop in replacement for Vintage Filter'Trons, HS Filter’Trons, and will fit in almost any Professional Gretsch guitar that is made for Filter’Trons.

    Humbucker Replacement: The Ray Butts Ful-Fidelity can not replace PAF style humbuckers because of the shape and mounting style. If you are looking for a close alternative then undipped TV Classics (meaning no wax) would be the closest thing in our line.
