The Matrix Infinity Narrow Format PRO-MAN-INF is Fishman’s flagship undersaddle pickup/preamp package for both steel- and nylon-string guitars. It offers the player clear, transparent tone and dynamic string response. The easily accessible soundhole mounted rotary volume and tone controls allow the player to make quick adjustments. And… Fishman takes tonal control a step further by providing the player a switchable voicing feature to accommodate different guitar body sizes and various performance situations.

There’s a lot packed in to the Fishman PRO-MAN-INF system:

  • Undersaddle acoustic pickup
  • Active, endpin-mounted preamp
  • Soundhole-mounted rotary controls for Volume and Tone (unique Tone control cuts mids while boosting treble and bass)
  • Switchable voicing feature to accommodate all guitar body sizes and performance situations
  • Integrated LED low battery indicator
  • Solderless connections

The Matrix Infinity Narrow Format system is designed for use on classical guitars with 3/32” (2.4 mm) saddle width, 2.65” (67.3 mm) saddle length, and maximum E to E string spacing of 2.5" (63.5 mm).

Fishman Matrix Infinity Installation

Both the manufacturer’s and our recommendation is to have a qualified guitar tech or luthier perform pickup and preamp installations. Nonetheless, we recognize there are lots of players out there who work on their guitars and are capable of performing this installation. If you are adept with a hand drill, can follow instructions, and carefully consider the mechanical factors that can affect performance, there’s no reason why you can’t successfully install this system on your guitar. Please note that Fishman’s instructions, while clear and concise, are tailored for installations on steel string guitars. You will have to do a bit of mental transposing and apply the principles outlined in their installation guide as they would pertain to a classical guitar.
