Zoom FS-01 Momentary Foot Switch

The Zoom FS-01 is a compact momentary foot switch for compatible Zoom effects processors, recorders, and mixers. Despite some marketplace listings calling it an expression pedal, the FS-01 is a single-switch foot controller rather than a continuous expression pedal. It provides hands-free control of assigned functions through a compatible device's foot-switch or control input.

It is suited to guitarists, bassists, recording users, and performers who need to trigger functions without reaching for a front-panel control. On compatible Zoom guitar and bass effects units, it can be used for tasks such as bypass, tuner operation, delay hold, delay-input mute, and tap-tempo entry. The exact function depends on the connected Zoom device and its available control settings.

The FS-01 does not process or alter the audio signal, so it has no tonal or sound-character contribution of its own. Its role is to provide a direct momentary control command to the connected unit. This makes it useful for timing-sensitive actions such as tapping tempo, activating a hold function, or changing an assigned operating mode during performance.

Zoom identifies the FS-01 as a momentary foot switch for its guitar and bass effects devices. It is also supported by selected Zoom recording products, including LiveTrak L-12, L-20, L-20R, L12next, and R8 models for assigned transport, punch-in/out, or effect-related functions. Compatibility and available functions should always be verified in the manual for the specific connected product.

The low-profile FS-01 connects with a standard 1/4-inch TS connection and includes a 1/4-inch-to-1/4-inch cable. It requires no separate power supply or battery. Add it where a compatible Zoom unit needs an extra foot-operated control without adding another audio effect or expression-control circuit.

• Single Foot Control: Gives one assigned function convenient hands-free operation.
• 1/4-Inch TS Connection: Connects to compatible foot-switch or control-input jacks.
• Included Connection Cable: Includes a 1/4-inch-to-1/4-inch cable for setup.
• Zoom Device Support: Works with compatible Zoom effects, recorders, and mixers.

Design & Installation

The FS-01 uses a compact, low-profile foot-switch format with one switch and a black finish. Its documented product dimensions are 67 mm wide, 105 mm deep, and 26 mm high, helping it fit into pedalboard, desktop, and recording setups where space is limited. It is a passive control accessory and does not need external power.

Connect the included 1/4-inch cable between the FS-01 and the compatible FOOT SW or CONTROL IN jack on the Zoom device. Configure the connected device for its supported foot-switch function, if configuration is required. Do not connect it to an expression-pedal input unless that device specifically documents FS-01 support, because the FS-01 is a momentary foot switch rather than a continuous expression pedal.
