The Epiphone AJ-100CE Acoustic-Electric Guitar brings the look and sound of the Advanced Jumbo to everyone. Guitar comes with standard AJ features such as a select spruce top, mahogany back and sides, and a rosewood fingerboard. The AJ-100CE includes a cutaway body style and the Nanoflex pickup for electric amplification.
NanoFlex pickup
The term "Nanoflex" refers to its ultra thin (nano-like) profile and its flexibility that allows it to conform to any surface shape. This assures complete guitar-to-pickup-to-saddle contact. Unlike other undersaddle pickups, the Nanoflex design utilizes 7 highly-sensitive and ultraresponsive layers of sensor material to not only sense the vibrations of the strings but the vibrations of the guitar body as well. The Nanoflex is the first pickup to incorporate active amplification directly at the pickup. As a result, the signal does not pass through even a single millimeter of the wire and therefore, the signal quality is uncompromised.
