Mi-Si Electronics Design, Inc.(pronounced “My-Sigh”) was foundedin 2004 by a team of engineers with more than25 years of experience in the amplification field,developing revolutionary electronics specificallydesigned for acoustic amplification.
Mi-Si introduced a truly significant and uniquebreakthrough: a high-performance, fully activepreamp that does NOT REQUIRE BATTERIES.A special blend of new energy sources and ourability to design compact and efficient circuits makeour battery-free products a reality. To enjoy the benefitsof this battery-free technology all you have to do is powerup for 60 seconds for a full 8 hours of performance timeor 16 hours when using the Trio and Simple Jack.
The Mi-Si AcousticTrio System featuresan active, battery-freepreamp designedspecifically to workwith the L.R. Baggsundersaddle Elementacoustic guitar pickup.The preamp for thissystem uses Mi-Si’scustom piezolinearization scheme,allowing for the mosttruthful and accuratesound from the pickup.All you have to dois power up for60 seconds using theMi-Si Power Charger,providing you withup to 16 hoursof performance time.
This simple and compactmodel, a high-impedancebuffer incorporated intothe guitar’s endpin jack,also features Mi-Si’srevolutionary battery-freetechnology.
Power up for 60seconds and you arefree to play for anincredible 16 hours!
The Simple Jack takesthe concept of highlyefficient design to thenext level and willwork with any piezoundersaddle pickup.
