Okay here's what you do...first set the left dial all the way to the right where it says user. that's the user's presets and that's where you get to create your own preset. next you press the edit button. from there each section on the right dial has a certain section for effects. when selecting the chosen effect from the left dial, the 2 buttons on the right will let you select which effect type you want based on the effect section you set the dial too. then you use the middle and right dial to adjust the effects level. you can also turn off the effect by pressing both buttons on the right. once you are done editing your effects, you save your preset by turning the left dial the user's preset section. push the left button on the right side twice and your preset will be save. just remember to be on the user's presets when you do that.
