I was trying to edit the first factory preset US Double Nrm. I removed the first block a volume pedal, I tried to put a new model (distortion) I could not move my joy stick to it, it was like it was grayed out or not selectable. I am new to this so not sure what I might be missing. I was able to make my own preset from scratch no problem. I just wanted to add a second over drive after the input and I could not. Any ideas would be helpful...thank you. Steve
