The Matrix Infinity is the result of over 25 years of collective R&D from acoustic amplification leaders Fishman. This undersaddle pickup is poised to change the way you look at undersaddle pickups, offering superb string-to-string balance and tonal accuracy. Building off of the Acoustic Matrix pickups that came before, the Matrix Infinity now offers a new active endpin mounted preamp with soundhole-mounted rotary volume and tone controls. Acoustic players of any genre and guitar body-size can benefit from the amazing sound of the Fishman Matrix Infinity.
