Slicer (guitar effect)

The vibrator pedal is an effects pedal present on some musical instruments, which is similar to a vibrato, chorus, or autopan, it combines a modulation sequence with a noise gate or envelope filter to create an effect not unlike a helicopter, with rapid cutting out and coming in—on and off. Most have variable speeds and depths, creating different sounds.

Vibrator Pickup

Also called a sustainer pick-up. A electromagnetic string driver placed near the high fretboard of an electric guitar or mounted on a stand as in the Guitar Resonator. The magnetic field is driven by the guitar pickup signal which causes a feedback loop that vibrates the strings. It is controlled via circuit board powered by a 9v battery inside the guitar or by an external supply). Sounds vibrator pickups make have been compared to strings sections, without the slow attack caused by a bow. An actual vibrator has the same effect.
