A hybrid guitar is an electric guitar with the ability to produce a signal with the tonal quality of an acoustic guitar in addition to a typical electric signal from a magnetic pickup, allowing a wide tonal pallette. The signal from the two-pickup systems can be blended on board, or (sometimes on the same instrument) fed separately to two different effect and amplification lines.
Hybrid guitars typically use a piezoelectric pickup to generate the acoustic-like signal, the same type of pickup used in most electro-acoustic guitars. Such pickups can produce a reasonable facsimile of acoustic tone even in solid bodied instruments. Aftermarket piezo pickups allow conventional electric guitars to be converted into hybrid guitars.
