■ Piezo pickup system for acoustic guitar

~From the manufacturer site~
Mi-Si's Acoustic Trio is a groundbreaking battery-free acoustic guitar pickup.
This model includes a simple jack (battery-free active preamp built-in), an L.R. Baggs Element undersaddle piezo pickup, and a charging adapter.
The biggest feature of Mi-Si is a battery-free system that does not use any dry batteries or lithium batteries.
By charging for 60 seconds with the dedicated charging adapter, you can play for about 16 hours.
Also, by eliminating the battery, there is no need for wiring to the battery, which causes sound quality deterioration. There is no deterioration in sound quality due to changes in battery voltage. You don't have to worry about running out of battery every time you play. No need to attach a battery case. It is an epoch-making system that overturns common sense, such as no need to worry about liquid leakage.
Of course, nothing is inferior to the traditional sound.
Please try the sound of this eco-friendly Mi-Si pickup.
The width of the ribbon-shaped piezo element is about 2.4mm.
