Aux switches are 3-button footswitches used to control Eventide and Digitech devices. The aux switch replaces the Digitech FS3X, FS300, or FS3 — with three buttons for ‘up,’ ‘down,’ and ‘mode’ functions.

Saturnworks aux switches can also be used to the control a variety of other devices such as the EHX Grand Canyon and EHX Superego+. They also work as a replacement for the TC Helicon Switch 3 pedal–as well as any other device that can be externally controlled by an FS3 or FS3X.

The aux switch must connect to your device with a TRS (in other words, stereo) patch cable. If you need a TRS cable, we have them available here.

The aux switch comes in two sizes. Both are functionally identical. The larger ‘BB’ size (4.7″ x 3.7″) simply allows a bit more space between the switches, while the smaller ‘B’ size (4.4″ x 2.4″) saves on space.

New starting January 2021: upgraded soft touch momentary switches! We are now installing new higher-grade soft touch momentary switches in our soft touch momentary applications. We were able to source a higher quality soft touch momentary switch than any switch we’ve used previously. Our new switch is both very quiet and beefier than any other soft touch momentary switch we’ve seen on the market. 

The Saturnworks aux switch features boutique-grade components, including:

  • Heavy duty soft-touch footswitches.
  • A Neutrik TRS jack.
  • Sturdy cast-aluminum enclosures.
  • A 1-year warranty against manufacturing defects.

Want to soup up your pedal, or make it reflect your unique style? We have many customizations and upgrades available for our pedals. You can add a custom graphic or upgrade to premium jacks or switches, for example. Contact us with any questions.

Please note: The pedals in the images are stock photos, not the actual pedals you will receive. The pedals you receive may vary in their graphics, knob colors, and/or LED colors, where applicable. We have our graphics options listed here.
