"Bill Lawrence Products"

In 1986 Bill Lawrence (Willi Lorenz Stich) started making and selling the L-500 and other guitar pickups under his new company name OBL, located in West Germany. These pickups would also feature flat blades although wider and longer. The original L-500s were made with only Gibson guitar string spacing in mind. These new 2.225 inch blades would allow the L-500's to be used effectively in guitars with Fender string spacing as well.
