The Secret Agent, a neck single-coil that resides under the pickguard, stealthy, hidden from sight. (Get it?) Seymour went with a medium-output ceramic bar magnet to help the Secret Agent accomplish its mission. Because it’s further from the strings with less magnetic pull, this design provides a full, warm, almost jazzy neck-pickup tone, which perfectly complements the Esquire bridge model’s bark and snarl.
