Abstract: The invention concerns a sound pickup device for acoustic instrument (10), preferably a string instrument, in particular a plucked string instrument, such as an acoustic guitar, stroke or struck string instrument. Said device is characterized in that it comprises: at least two overhead microphones (1, 2) designed to be positioned above the instrument (10), outside the instrument (10), wherein said microphones (1, 2) are large bandwidth microphones one of which constitutes a preferably low frequency sensor, the other preferably a high frequency sensor in such a way that a wide spectrum of bass and trebles is covered; and at least another relay box (6) whereto each microphone (1, 2) is connected, said relay box (6) being adapted to transport sounds in parallel receiving, in parallel, in input, the signals of the microphones (1, 2) and being adapted to transmit, in parallel, in output, by wire our wireless connection to a mixing console or to a preamplifier.
