You’ve turned the input level down too low. It’s in the I/O sub-menu. Pick a higher level.
Yes because it’s a signal to noise ratio setting. I believe the manual explains this.Never mind I think I figured out how to get in setup mode, then instrument input. The LED's are bouncing now. What I don't get was when I opened the setting it was set to 12. As I played my guitar wide open on the hottest pickup I rotated the setting and I heard no perceptible change in my guitar whether I set it to zero or 12..... I put it on 6 and the LED just touches the red when I whack it.
