The BOSS FS-7 is a compact dual footswitch with two pedals arranged in tandem to save pedalboard space. Its Silver chassis and Black A/B pedals provide remote switching for compatible effect pedals, amplifiers and other equipment with a suitable control input.

A common mode selector chooses latching or momentary operation for both pedals, while the polarity selector lets you match a compatible device. The rear panel has a 1/4-inch A jack and a 1/4-inch TRS B jack for combined A/B switching, plus DC power input. Check the controlled device's required connection, polarity and mode before use.

The FS-7 can operate in momentary mode without a power supply; its indicator LEDs remain off in that mode. Latching operation and illuminated indicators require a suitable BOSS PSA-series 9 V adapter, sold separately. The durable steel chassis has a compact 62 × 131 mm footprint and stands 57 mm high with the rubber feet fitted.

Includes one FS-7 footswitch, four rubber feet, a parallel DC cable and manufacturer safety documentation. The pictured DC cable is a power splitter, not an AC adapter or a footswitch signal cable. A power adapter, signal connection cables and the controlled instrument or effect unit are not included.
