A pickup device for an acoustic guitar having metallic strings comprises an electromagnetic pickup detachably attached in a sound hole of the guitar and a piezoelectric pickup detachably attached in the sound hole or to another part of a sound board of the guitar. Outputs of the two kinds of pickups are mixed at a selectable ratio thereby to compensate for difference in the picking-up characteristics of the respective pickups.
