Mark IV footswitch problems.

[Grandor]

Ok, so I had a big gig the other night (1000+ indoor).
And I show up to soundcheck and my FU-3 will only let me select RHY2 or LD-EQ. No LEAD and no RHY1 !

The switching on my amp (manually) lets me select the channels. But When I hit RHY1 or LEAD on my footswitch the LED does show up on my footswitch but doesnt change at all on my amp!

Has anyone experienced this b4 ?

Never had that problem, but let us know what you find out, it may save some of us Mark IV owners some future grief.

IT would appear that one of the wires on the amp-in end has come loose.
I resoldered and tried... No power whatsoever on the footswitch...

I took it apart again and... A DIFFERENT wire had come loose, so now im doing that one again...


Just For reference purposes, there is one wire which runs end to end through the cable but is not attached to anything. Bear that in mind when you take yours apart. If you ever need too.
