The Reincarnation of Motif

January 17th, 2017

NEEDHAM, MA – Mi-Si announces Motif2, a wholly redesigned first condenser type, high-performance under saddle pickup and endpin-mounted preamp featuring Mi-Si’s now classic battery-free technology.

This breakthrough pickup offers all the benefits of conventional under-saddle applications without distortions inherent in piezo sensors. It’s highly responsive with low feedback, and it allows the player freedom of movement without impairing your instrument’s appearance. It is only 1 mm thick, providing superior contact with your guitar’s bridge and saddle, with much less impact on its structural integrity.

Charge Motif for 60 seconds via the output jack and you’ll have up to 8 hours of exceptional acoustic amplification.
