Features 1、Time Knob: This time control roughly sets the length between repetitions between 40 milliseconds and 600 milliseconds, which is very suitable for classic and classic delay sounds, and very suitable for return or medium length delay time. 2、Depth Knob: Turn this control button to achieve deeper and deeper and pitch transformation on the echoes. As you increase the control, the depth and rate LED will begin glowing, giving you a visual indication of the amount of modulation you are applying repeatedly. 3、Full Metal Shell: This is a delay effect guitar effect pedal with a full metal shell, which is compact, durable and easy to carry. 4、Speed Knob: This is the flutter control. This is another way to control the echoes performance of the tape. Using these controls can create unique music delays. 5、Regen Knob: This control sets the number of repetitions. You can set to a single return echoes, or can be set to runaway, self oscillation or self regeneration echoes. (Now go back and twist the time controls to get some crazy sounds.)
