Result of 25 years of R&D
Resulting from over 25 years of collective R&D, the newly redesigned and re-voiced Matrix Infinity undersaddle pickup offers exceptional musicality, superb balance from string to string, absolute accuracy and ease of installation. Starting with the popular Acoustic Matrix pickup as a point of departure, the Matrix Infinity now includes a new active, endpin-mounted preamp for the most sophisticated level of sound quality and responsiveness to the player's touch.

Exceptional sound and versatility
Key to the evolved design of the new Matrix Infinity are soundhole mounted rotary Volume and Tone controls that now allow the player to make a variety of easily accessible dynamic and tonal adjustments. The Tone control cuts mids while boosting the bass and treble response to enhance the tonal characteristic and impact of any amplified acoustic guitar, from classical nylon string instruments to Dreadnought and Jumbo acoustic models. Taking the pickup's tonal variation capability one step further, the Matrix Infinity also incorporates a switchable voicing feature to accommodate all guitar body sizes and different performance situations in one pickup.

Two models available
Exceptionally roadworthy, the Matrix Infinity is available in two saddle slot widths - a wide 1/8" format or narrow 3/32" format - the Matrix Infinity has a standard overall length of 2.65" that will fit most guitars with string spacing of up to 2.5". The Matrix Infinity requires a 9V battery (not included) and professional installation is recommended.

Fisherman Matrix Infinity Just Incredible

Simply put, I was searching for the very best way to amplify my new Ibanez Atwood 400 Series Grand Acoustic Guitar. It features a size, shape and playability that provides an amazing tone for a value-priced, stunning instrument. With its violin, vintage gloss brown burst finish, this guitar is jus unplugged. I wanted that same tone when playing it plugged and was seeking to a proven performer to best amplify it. I've owned Matrix Infinity pickups before and had one that sounded just great in a previous Martin 000-15M that I once owned. Man, am I ever glad that I went with this Fishman pickup again. It just pairs up so beautifully in reproducing the tone of this guitar s incredibly well when amplified. I also like the way it sounds running it though my BodyRes pedal. Very warm, crisp sound and easily adjustable with built-in volume and tone controls.

Great for Baritone Acoustic

Ryan Murphy suggested this for my baritone acoustic and he was on point. I installed myself. A little tricky but not too tough if you have the right tools and follow instructions. Works flawlessly and perfect match for the baritone. great pickup - a workhorse and it delivers.

Great Pickup!!

I spent months searching for a pickup to my hand crafted made in Puerto Rico acoustic guitar (nylon strings). I mostly use the guitar to play folk music and i needed a pickup that emphasize bass notes without sounding too boomy. I considered lr baggs element and other models, but at starting point, the Matrix Infinity has all features i need, bass boost and a Mid Contour knob. So, i decided to buy it. Installation was easy. The undersaddle will high aprox 2mm the strings so you have to trim the bone if you don't want to loose the action you had before. The trick is to trim the bone saddle perfectly, so the strings are all equal volume. This part took a little time, because i need to sand very accurate with a lot of patience to get it perfect. I setup the preamp to bass boost and installed it. Solderless install was a good part.When i test the sound i was very impressed! It get exactly the sound i'm looking for. If you don't want that bass boost, simply leave it flat. But for me, is a must. Also i was very impressed with the contour knob. I hate the LR baggs Element Tone Knob that i have in other guitar. Is useless for me. The contour knob do a lot more to shape the sound you want. Is excellent for me. I highly recommend this pickup!!
