Sustain Pedal MARANTZ Kurzweil KP-3 — single-pedal sustain for keyboards and digital pianos

The Sustain Pedal MARANTZ Kurzweil KP-3 is a single-foot sustain controller designed for keyboards and digital pianos that accept a standard 1/4" TRS or TS sustain input. It provides straightforward on/off sustain function to extend note hold and shape musical phrasing during practice, rehearsal, or live performance. The KP-3 connects via a wired cable for reliable signal transmission and features a sturdy housing intended for regular use in stage, studio, and home environments.

Advantages

The KP-3 offers simple plug-and-play compatibility with most keyboards and digital pianos that use a standard sustain jack, ensuring immediate operation without complex setup. Its mechanical design delivers consistent on/off response for predictable sustain behavior, while the robust construction and cable connection minimize the risk of intermittent contact during use. The compact footprint allows placement close to the instrument without obstructing pedalboards or stage setup.

Suitable for

• Keyboardists and pianists seeking a basic sustain pedal for practice and performance
• Home studios and rehearsal spaces requiring a reliable foot controller
• Live performers who need a durable, compact sustain solution
• Educational settings where a straightforward, easy-to-use pedal is needed

Key specifications

• Connection type: wired 1/4" TRS/TS plug compatible with standard sustain jacks
• Control type: on/off sustain (momentary footswitch behavior)
• Housing: durable construction suitable for stage and studio use
• Form factor: single-foot pedal with compact footprint

How to use

Connect the KP-3 pedal to the sustain input of your keyboard or digital piano using the attached 1/4" plug. Place the pedal on a stable floor surface in front of your playing position and operate with your foot: press down to engage sustain and release to stop sustaining notes. No additional drivers or configuration are required for most instruments; consult your keyboard's manual if polarity reversal or alternate sustain behavior is needed.

Usage recommendations

To extend the life of the pedal and maintain consistent performance, avoid exposing the unit to excessive moisture or direct impact, and store it in a dry place when not in use. If your keyboard produces inverted sustain behavior, check its settings for polarity or try a polarity-reversing cable or adapter if supported by the instrument.
