There are three knobs to control the digital delay: • FX Master: Adjusts the balance of the "wet" and "dry" signal. • Time: Adjusts the time interval of the delay. Turn this knob to the right to increase the time interval between two delays. • Repeat: Adjusts how long the delay sustains. Turn this knob to the right to make the delay repeat for longer. 10.
