MI-SI ELECTRONICS DESIGNMotif
Battery changes aren’t required for this undersaddle pickup/class-A preamp combo that requires just a 60-second charge via the output jack for six hours of acoustic amplification.
This system’s AT93 pickup uses piezo film in a layered (bimorph) format that allows for lower-output impedance. Because the film runs the length of the pickup, any number of strings or any string spacing can be used.
