“A Mel Lace Innovation”

Check out this small, obscure ad from Guitar World, January 1992. The Adder, says the copy, “slides over your existing pickups altering their characteristic sound for as long as you desire.” Apparently, The Adder was designed by Mel Lace, brother of Don Lace who created the Lace Sensor pickup famously used on a generation of Fender Stratocasters.
