My issue is not with saving custom patches to amp channels - that works just fine.
My problem is when I try and save my tweaked effects settings to the Effects knob. Following the steps in the Line6 manual, I hold "Save", hit "Manual", ABCD buttons all flash as they should. When I hit "B", the "B" button remains lit, others go out, then I hit "Save". That's supposed to do it.
Problem is, nothing seems to get saved to the effects knob. I turn the effects knob and the effect that plays is the original, not my modified one.
If it was a problem with the onboard battery, would that not prevent me from saving amp settings too? (Which I can do fine)
Example, I want the delay settings default to be 180ms / 36% feedback, 18% depth. I get that sound dialled in, and follow the save procedure. When I turn the effects knob away from delay, then back, the delay time is back at 400ms.
