Pedal switch. Use the 2-channel remote switch to control the Descent and Vanguard's two foot switches. This feature allows you to place the Descent at the back of your pedal board and run the small remote control switch to the front of your board; freeing up real estate on your board's front row. To use the Remote option with this 2-channel remote switch, a TRS cable is required. For the Descent and Vanguard this pedal remotely controls the Preset footswitch and the Bypass foot switch.
