Shadow Electronics is a German manufacturer of pickups and preamp systems for acoustic and electric instruments, founded in 1971 in Erlangen, Germany by Joe Marinic. The company built its reputation on transducer pickups for acoustic and classical guitars, and is credited with developing an early undersaddle piezo pickup that helped popularize amplified acoustic playing. Its catalog spans soundhole pickups, undersaddle transducers, magnetic and piezo bridge systems, onboard preamps, and tuners aimed at folk, classical, and orchestral musicians.

The brand is most closely associated with two proprietary sensor technologies: NanoFlex, a thin flexible transducer that contours around an instrument's bridge or saddle to capture body vibration, and NanoMag, a low-profile magnetic pickup designed for a more linear frequency response on steel-string acoustics. Shadow applies these designs across guitars, basses, ukuleles, banjos, mandolins, violins, cellos, and upright basses, often as OEM electronics inside instruments built by other manufacturers.

Products are manufactured in Germany and sold worldwide through music retailers and luthier supply channels, with U.S. distribution handled by Traveler Guitar. Shadow's pickups are a common aftermarket choice for acoustic players seeking to amplify their instruments without permanent modifications.

Shadow has 8 products cataloged on Equipboard, including Acoustic Guitar Pickups, Tuners, and MIDI Interfaces. Their gear is featured by 3 artists, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include Steve Stevens, Shawn Mendes, and José González.
