Expression pedal BOSS FS-7

The BOSS FS-7 is a compact dual footswitch designed to provide remote control for effect pedals, amplifiers, and other stage equipment. Its small footprint places two footswitches in tandem to save space on pedalboards while retaining full functionality. The unit supports both latch and momentary switching, runs without a battery for reliable board use, and is powered by a 9V adapter (power splitter included). It also functions as a momentary switch when unpowered.

Advantages

The FS-7 offers dual footswitch functionality in a compact steel chassis, combining durability with minimal pedalboard real estate. It provides selectable latch or momentary modes common to both switches, supports battery-free operation for cleaner setups, and includes a 9V adapter power option with a splitter. When not connected to power, the device still operates as a momentary switch.

How to use

Place the FS-7 on your pedalboard and connect its 1/4" outputs to the devices you wish to control. Select latch or momentary mode (the setting applies to both A and B switches) according to the required behavior. Connect a 9V adapter using the included power splitter when external power is needed; if left unpowered, the footswitches will function in momentary mode. Use the two tandem footswitches to toggle effects, switch amp channels, or send switching signals to compatible devices.

Recommendations

For reliable stage performance, mount the FS-7 on a stable area of your pedalboard and use the supplied power splitter with a regulated 9V adapter from a reputable brand. If you need only momentary operation, the unit can be used without external power to simplify cabling.
