Fishman Split saddle format – undersaddle pickup

An amplification solution for split-saddle bridges

The Matrix Infinity in split-saddle bridge format is designed for guitarists who want to amplify an acoustic guitar equipped with a two-part bridge saddle. This configuration requires a pickup suited to the instrument’s geometry: the two piezo sections sit beneath the corresponding portions of the saddle.

For performing on stage, rehearsing with a group or integrating your acoustic guitar into an amplification chain, this system brings together the essential elements for sound capture and preamplification. Before installation, check the dimensions of your bridge and saddle slot to confirm compatibility with the pickup.

Under-saddle pickup and easy-to-reach controls

The piezo pickup is positioned under the bridge saddle, where it captures the vibrations transmitted by the strings. Its split format comprises a 44.5 mm section and a 22.3 mm section, both 2.3 mm wide. These measurements are crucial when choosing a solution suited to your guitar.

The preamp unit is installed inside the instrument, while the control module is positioned at the edge of the soundhole. This layout keeps the controls accessible without requiring a remote control box. Careful installation, particularly where the saddle rests on the pickup, is important for achieving a balanced response across the strings.
