Boss FS-5L Latching Footswitch

Boss FS-5L Latching Footswitch | No Limit Guitar Co, Idaho Falls

The Boss FS-5L is a single-button latching footswitch designed for use with Boss amplifiers, effects units, and any other compatible equipment that accepts an external latching footswitch connection. Unlike the momentary FS-5U that activates only while held, the FS-5L latches — one press engages the function, one press disengages it — making it ideal for functions that need to stay on or off between presses rather than only activating during contact. An LED with switchable polarity indicates the current on/off status, highly sturdy construction handles regular stage use, and a standard 1/4" connector means it connects via any ordinary guitar cable. Two AAA batteries power the LED status display.

Product Overview

Boss offers two footswitch options specifically because different applications require different switching behavior. The FS-5U is momentary — the connected function is active only while the footswitch is physically depressed, and deactivates the moment the foot lifts. The FS-5L is latching — each press toggles the connected function between on and off states that persist until the next press. For functions like channel switching, effects loop bypass, boost activation, or any other application where you need a function to stay engaged across extended passages without keeping your foot on the switch, the FS-5L is the correct choice.

The LED status indicator with switchable polarity is the practical feature that makes the FS-5L genuinely useful on a dark stage — the LED confirms at a glance whether the connected function is currently active or inactive, eliminating the uncertainty of wondering which state the switch is in mid-performance. The switchable polarity accommodates equipment that uses different LED logic — some devices illuminate the LED when the function is on, others when the function is off, and the polarity switch allows the FS-5L's LED to match the visual logic of the connected device. The LED requires two AAA batteries for operation — the footswitch itself functions without batteries, but the status LED will not illuminate without them.

Highly sturdy Boss construction means the FS-5L handles regular stomping and stage use without the mechanical failure that cheaper footswitch alternatives develop over time. Standard 1/4" phone jack connectivity accepts any ordinary guitar cable for connection to the footswitch input of compatible equipment — no proprietary cables, no special adapters required. Always consult the owner's manual of the connected device to confirm FS-5L compatibility before purchase.

Ideal For
