Our Philosophy
In the past, conventional circuit design components have been a burden to acoustic musicians, incurring extra cost, requiring additional space, and decreasing reliability and tonal quality. Making a signal pass as simple as possible has not been a luxury, but a necessity. This knowledge is the driving force behind Mi-Si’s approach – minimalist design with maximum functionality. Musicians have known this all along, the fewer obstacles between your pickup and your amp, the better your sound.
Battery-Free
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.
0 to 60
To enjoy the benefits of Mi-Si’s Battery-Free Technology, all you have to do is power-up for 60 seconds, providing you with 8 hours of performance time (or 16 hours in the case of the Simple Jack). Our extremely energy-efficient design not only means no batteries, but no battery wires, no dead or fading batteries, no RF interference, no battery compartments, and no need to remove a battery from your instrument before transportation.
Good News for the Whole Planet
Every used battery is a hazardous waste and needs to be properly disposed of to avoid toxic chemicals leaking into soil and waterways. Our environmentally conscious and advanced designs eliminate this waste. Our products are created with one goal in mind – to provide the highest quality performance while being as frugal as possible regarding energy consumption. We are proud to play a role in furthering the aspirations of musicians, in addition to helping our planet.
