Use the Delay Level knob to set the desired level of the delay signal. Unlike the delay level knobs of some other pedals, the Delay Level knob of the Flashback X4 Delay & Looper will not influence the volume of the dry (unprocessed) signal. Analog-dry-through allows the analog signal from your guitar to pass through the pedal without being digitized. This means zero latency and no tone coloration.
