I have to wonder what you're thinking!! You build 5 string "J" pickups, the Area J 5 and Ultra Jazz 5, that won't fit the Fender Jazz Bass 5 (V)! Are you mad about something? I almost ordered a pair of the Area Js, until a reviewer wized me up about the size. If they would fit, I would have a pair on my bass now! So I went with Seymour. They're in the mail. Could have been you. I have to believe this isn't the only sale it cost you. Your friend, Jon PS. To all the helpful TBers who are just dying to point out that this has been discussed before, thank you in advance for your input.
