What Martin 12-string models is this kit compatible with?

This kit is designed specifically for Martin Era collection 12-string models. The pre-contoured saddle and bridge plate are matched to Martin specifications for proper fit and alignment without guesswork.

How much modification does the installation require?

What does the pickup system sound like, and will it color the tone?

The under-saddle piezo captures vibration directly from the bridge for balanced representation across all 12 strings with minimal coloration, delivering natural amplification suitable for both live performance and studio recording.

What output connections and amplifier compatibility does it have?

The kit includes a standard 1/4-inch jack assembly with shielded cable and high-impedance output compatible with any standard amplifier, acoustic amp, interface, or mixing console.

What components are included in the kit?

The kit includes a pre-contoured saddle sized for 12-string bridge spacing, the under-saddle piezo pickup element, integrated 1/4-inch jack assembly with shielded cable, custom pickup bridge plate, installation hardware, adhesive, and complete documentation.
