State of the art, battery-free technology for acoustic amplification. After more than 25 years of designing and building preamps, Mi-Si’s team of engineers proudly introduces a truly significant and unique breakthrough: a high-performance, fully active preamp that does NOT NEED BATTERIES. No 9-Volt, no AA, no AAA, no lithium – NO BATTERIES at all. A special blend of new energy sources with very low-power components and our ability to design compact and efficient circuits make our battery-free products a reality.

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. The Flux 2.0 pickup employs a unique “planar” single coil design – less susceptible to AC hum than traditional bobbin wound pickups. 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. Power up the Acoustic Duo for 60 seconds with the Mi-Si Power Charger for up to 8 hours of performance time.  SRP €189.00
