Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Boss FS-5U.

Features and functionality

  • The FS-5U sends two signals: one when depressed and another when released, affecting trigger behavior.

    Source
  • The FS-5U is a passive momentary switch that shorts the tip to the sleeve, lacking debounce circuitry.

    Source

Software and compatibility

  • Connecting the FS-5U to the SPD-SX's footswitch 1/2 input allows it to function as a trigger.

    Source
  • Disconnecting cables without powering off the Boss looper can cause malfunctions, as per the manual.

    Source

Setup and maintenance

  • Changing the polarity on the FS-5U ensures the trigger occurs upon depression rather than release.

    Source
  • Ensure the FS-5U is set to "normally closed" to avoid issues with Boss loopers, as they require this setting for proper operation.

    Source

Use cases and applications

  • The FS-5U can trigger samples on the SPD-SX without using hands, useful in live performance scenarios.

    Source
  • Shorting a regular guitar cable's tip and sleeve can simulate the FS-5U's momentary switch function for troubleshooting.

Perfect pedal extension

Bought this to use with my RC-1 Loop pedal and it's really helped me unlock the loops potential. I've also used it as an expression pedal on a few keyboards and it does that pretty well too.

Stirdy and reliable

This is the no-compromise go-to pedal for a non-latching footswitch. Built like a tank, it will most likely outlive you and your band members, even if you all go to war. With a side switch to toggle between "normally open" and "normally closed" states, this pedal covers every use you can imagine.

Does the job well, and it tough

This pedal is good., but there are better Boss switches now, such as the FS-7 dual footswitch with non-latching and latching functionality.

jamesnotjim

Does what I need. Built like a tank.

Right now, I use this as a tap tempo for my Boss AW-3 Auto Wah. I've used it for lots of other things in the past. It's solid and, if you need more than one, you can lock them together with a mechanism that's part of the case design.

Use it for all your unlatching needs!

I use the FS-5U with my Boss DD-7 perfect for tap tempo!

And Jesus wept

for there were no more mountains to conquer in the world of single-non-latching foots-witches. Life cruel sometimes -this is how life compensates. Thanks life.
