So, i got a stereo cable to use for the fs input on the Digitech Jamman. In my preset, i make two footswitches that send the connections to the pedal to change the loop up and down. Works like a charm... Unless i press any other button on the Snapshot menu. Any of the footswitches, even the 'next snapshot' button sends the Jamman into a perpetual count up or down. If i go back to the stomp box mode and click the buttons to change up and down they work, but wont break the cycle. If i switch presets, it resets and works again, until i push a snapshot button. What's going on here with the Ext Amp output jack??
