Pickup development began in the summer of 1979. "K&T Pickup", a store specializing in old guitars, was in charge of development. It was Mr. Jun Takano, known for "vintage guitars". With the cooperation of Fujigen's top engineer Toshihide Ushimaru development proceeded.
After trial and error, the initial prototype was completed. A prototype guitar with that pickup was developed and Don Felder of the Eagles had the chance to try it out. There is an anecdote that Don Felder liked it and brought it home.
Early prototype pickup. Mr. Takano, who was a little dissatisfied, decided to follow Mr. Ushimaru's suggestion. They used a small amount of USA wire that was in the factory as a trial. Changed to USA wire, the sound is quite satisfying, which is what Mr. Takano is aiming for. A pickup with rich overtones was completed. This is a pickup called DRY later.
When Santana tried this final prototype, he said he wanted it and sent it to Santana. This pickup which was recognized by overseas musicians, was named DRY instead of the previous number. The early pickups had a Z stamp on the base plate and looked like nothing out of the ordinary.
