Flashback X4: There’s no delay, what’s wrong?

When none of the three footswitch LEDs are lit, the pedal is in bypass mode, and you will only hear the dry, unprocessed signal.

If you have set the pedal’s internal Kill-Dry dip switch to the “On” position and none of the three footswitch LEDs are lit, no signal will be present at the Flashback X4 Delay & Looper’s output.
