Product Description

Boss FS-5U, Foot Switch

A robust foot switch with many areas of application. Many keyboard players will use it as a sustain pedal, but since most effects pedals these days can be used more effectively when used in conjunction with an additional switch, other people - such as guitarists - can also put this product to good use. Consider the tap function of various delays, where pressing the button several times can adapt the delay time to the exact tempo of the song.

Frequently Asked Questions

No, it's a momentary switch, so it provides on/off control, not continuous volume sweeps. It’s not designed for volume pedal functionality.
The cable is relatively short, around 6 feet, which is standard for foot switches. You might need a longer cable depending on your setup.
Switching polarity reverses the signal output, useful for compatibility with certain effects or keyboard setups that require a normally-open or normally-closed trigger.
