The C-Ducer CP series comprises specialized contact microphones, or "pickups," designed to capture sound by directly sensing the vibrations of a solid surface. Unlike traditional microphones that capture sound waves from the air, a contact microphone is attached physically to an object—such as a guitar body, violin bridge, piano soundboard, or any resonant surface—and converts its mechanical vibrations into an electrical audio signal. This makes it an invaluable tool for amplifying acoustic instruments in live settings with high gain before feedback, for unique sound design by "listening" to unconventional objects, and for scientific measurement of vibrations.

C-Ducer models are known for their thin, flexible, and durable piezoelectric film design. This construction allows them to conform to curved surfaces and be placed discreetly without significantly affecting the acoustic properties of the source. They provide a very clear, direct representation of the instrument's natural resonance and attack, often with a pronounced low-end response and detailed transient detail. Because they pick up almost no ambient room noise, they excel in noisy environments and offer exceptional isolation, which is also beneficial in studio recording for capturing a pure, uncolored instrumental tone that can be blended with other microphones.

These contact mics typically feature a standard 1/4" output jack for direct connection to an amplifier, mixer, or recording interface, though some models may include XLR outputs or preamp interfaces. For musicians, sound artists, and audio engineers seeking a reliable, feedback-resistant method of amplifying acoustic instruments or exploring experimental sound sources, C-Ducer contact microphones provide a unique and practical solution that accesses sound at its point of origin.
