The EBow is an electronic device used for playing string instruments, most often the electric guitar. It was invented by the American guitarist Greg Heet in 1969 and introduced in 1976. The EBow uses a pickup and a magnetic feedback circuit to vibrate strings without touching them, allowing players to sustain notes indefinitely.
