Abstract
Abstract A cordless electrical guitar and amplifier system which eliminates the use of connecting electrical wiring between the guitar and amplifier unit. An output transducer, linked to an internal radio transmitter which is powered by batteries is contained within the guitar. A radio receiver in a remote amplifier unit receives the radio signal from the transmitter in the guitar and converts it through an attached loudspeaker to the audio signal.
