The Mi-Si Acoustic Trio system features an active, battery-free preamp designed specifically to work with the L.R. Baggs undersaddle acoustic pickup. The preamp for this system uses Mi-Si's custom piezo linearization scheme - allowing for the most truthful and accurate sound from the pickup. All you have to do is power up for 60 seconds using the Mi-Si Power Charger, providing you with up to 16 hours of performance time.

It comes with a UK adaptor to connect the preamp to the mains (it is really simple, a plug on one end, a jack plug on the other - stick it in for a minute and you can play for 16 hours).

This is used by one of our ukulele experts, in the exactly same ukulele as his colleague, who has a Fishman fitted. When they play as a duo, the clarity and honest reproduction of the acoustic tone is marked, quite simply the MiSi fitted uke is much, much better! (Update! It is now used by both of our ukulele experts - the one with the Fishman gave up and got one of these!)
