So, with all the FX in the chain showing, three of them will be highlighted. You can scroll left or right (bottom row, far left 2 pedals) to highlight the three you want to have access to, the highlight will move as you scroll. When you have the three chosen, hit the far right, bottom row pedal to choose these. Once you do this, the three FX will then correspond to the upper rows of 3 switches to turn off and on as you please. Hit the far right (bottom row) switch again, and the parameters will show up for adjusting. Keep in mind that an amp sim is two slots, so you will need to scroll L or R to get all of the parameters to show. All the extra work is worth it in the long run, and it really is easier than it sounds. It can all be done on the fly. Please feel free to PM me if none of this makes sense, or you have further questions. I love this box, and would like to see it work for everyone.
J!
