An easy-to-install Nanoflex pickup and preamp for steel string and classical guitars. Nanoflex pickups not only respond to string vibrations, but also sense the vibrations of the body of the instrument simultaneously. This completed shielded system incorporates active amplification in the pickup itself, which makes it 100% hum and noise free. The flexible NFX-AC pickup mounts under the saddle and the attached, extremely light preamp mounts to the end of the bridge. Volume control. Easy to install, no drilling or milling required. Includes separate output cable 12’ (SH 007) 3V battery included.
