The Echolution 2 and Echolution 2 Deluxe delay pedals from Pigtronix have two “hidden” features: Jump (raises the pitch of repeats by an octave each time a repeat regenerates) and Freeze (holds whatever audio is being played when the switch is depressed). To access those features you need the optional Echolution 2 Remote Switch.
Connect the Remote to your Echolution 2 using a 1/4″ TRS cable. The default function for the remote is to switch among the first four presets in each bank and to change banks. However, if you hold down the Tap footswitch on the Echolution 2 while powering the unit up, the Remote will change to turning Jump and Freeze on and off. To switch back to preset control mode, hold the Tap button and power up the Echolution 2 again.
