The sound of an electric guitar can be modified by new playing techniques such as string bending, tapping, and hammering-on, using audio feedback, or slide guitar playing.

Electric violin Braia, Kernunna, Carol Carolo, Os Minervas, Leonardo Araujo, Transfonika Orkestra, Sagrado Coração da Terra, and others.

This design was later refined and turned into a commercial product. Unlike most pickup designs, the Zeta pickup has the ability to output the signal from each string on a separate audio channel. Using a multi-pin cable to their pitch-to-MIDI interface, this allows for polyphonic MIDI control with each string set
