Acoustic Duo

The Mi-Si Acoustic Duo system includes the revolutionary new Flux 2.0 active battery-free magnetic soundhole pickup for acoustic guitar with the Mi-Si power charger.

This design combines the benefits of a single coil pickup with the virtually hum-free operation of a humbucker. It is an ACTIVE magnetic pickup, so you don’t have to worry about the cable capacitance or input impedance of your system – the pure and natural sound of your acoustic guitar will not be altered.
