I can’t get my QU-SB to respond to footswitch commands. I’m using a Boss FS-6 and it works with other amps. I’ve used the QU-PAD app Setup>Control>Footswitch to assign mute groups and mute channels but it will not switch. I’ve used the “calibrate” feature to select “latching/momentary” etc. but to no avail. I also tried just connecting the wires directly.
Does the footswitch function have to be enabled elsewhere?
