Boss FS-1-WL Wireless 3-way Footsw.

Very configurable bluetooth foot switch.

You can send either MIDI controls or keyboard inputs, which makes it easier to customize and adapt to other usages, and with a MIDI cable you can use it to send commands to other different hardware.

I bought the FS-1-WL in order to use it with my Boss GT-1000 pedalboard. It does the job and it works ok, the good news to me is that I can connect my external footswitch (Boss FS-7) as well so I can use them both wirelessly and over a big distance by the GT-1000.
Nice quality and feeling, still I can not say abt the battery lifecycle

amazing little helper, works fine, connects seamlessly and provides meticulously !

I use this to switch presets in Neural DSP plugins (Archetype etc.). You can connect it to a Mac as well via Bluetooth and then route MIDI messages in your DAW and wherever else. The app works fine. I like that you can configure most of the common types of MIDI messages. Also really cool that you can connect an external expression pedal and send CC sweep messages. What I don't like so much are the rubbery buttons. The actuation of the buttons feels spongy, especially barefoot.

I needed a small guitar fx setup for home, and this footswitch along with the katana go fitted my needs nicely.
