Thanks a lot for answer. Coutness MKII has two footswitch jacks. First is for channell switching (2 - way latching) and second for change of EQ map (original MKI x new MKII - nomod function). Nomod footswitch jack is one way latching.Looks like that amp has a single 1/4-inch footswitch jack, an AC-1QTRS cable would be sufficient.
