Abstract: An electric guitar with steel strings feeds into a stereophonic amplifier and loudspeaker system with two channels and is fitted with a pickup which senses each guitar string individually and proportions the signals from each string differently, so that each guitar string sounds from the loudspeakers as though that string is in a different position from all the other strings. For each guitar string the pickup has a respective pair of coils of varying numbers of turns and a respective permanent magnet. Electrical connections to the coils enable one channel to receive a signal from one coil of each pair and the other channel to receive a signal from the other coil of each pair, so that there are two composite signals, one per channel.
