The man who developed the Lace Sensor is Don Lace Sr.

Don Race Sr. had been involved with Fender since 1967, working on improving amplifier speaker designs, consulting, and solving pickup problems.

In 1979, he founded Actodyne General International (AGI) and began developing pickups in earnest.

AGI was initially founded in the garage of his home, where he and his two sons, Don Race Jr. and Jeff Jr. were building functional components called solenoids.

Don Race consulted with Leo Fender and Don Randall when problems with coils often arose in the manufacture of solenoids.

Fender was also having problems with pickup returns, so he would consult with Don Race.

At the same time, Fender was looking for low-noise pickups, and Don Race was the obvious choice.

Don Race develops pickups with a "micro-trick comb," a comb-like bobbin with 36 teeth on the top surface of the bobbin.

This microtric comb allows more information about the string vibration to be read than a regular single coil.

Since it could be finished with fewer turns than the number of coil turns, noise could also be reduced.

This is the famous lace sensor.

Fender liked the innovative construction of the Race Sensor, which also incorporated the principles of Fender's single coils, and its modern look with no visible pole piece, and signed it to an exclusive contract with Fender for 10 years from 1986 to 1996.

The Lace Sensors made during this period are marked "Fender Lace Sensor" on the top of the pickup.

And there is one person who played an essential role in the adoption of lace in Fender. That person is Seth Lover, who is also famous for developing the "P.A.F." system. Seth Lover has worked for Fender since 1967, developing such products as the "Wide Range Humbucker.

When Race was experimenting with the Race Sensor, the guitar on which the pickup prototype was mounted was the original guitar that Seth Lover had. Seth was impressed with the pickups there, and this was one of the reasons why Race was used on Fender guitars.

The Lace Sensor was used by Eric Clapton, Jeff Beck, and many other artists, and quickly became well-known.

In 1992, Don Race Sr. passed away, but his two sons continued to take over Race. And they continue to develop innovations that are still ahead of their time, such as the "Trans Sensor," which uses 95% fewer coils in pickups and has passive yet low-impedance characteristics, and the "Aluminum Tone.
