    Repair: TC Ditto x2 footswitches

    by Jane is K.O.

    TC Electronics’ Ditto loopers oftenly show faulty footswitches.
    This chronical, much discussed issue, occurs with some other TCE pedals as well.
    TC Electronics don’t seem to do much about it.
    I have three Ditto x2, all sound and play great.
    And ALL have the switch problem.

    Broken unit on left, repaired on right

    Obviously, when pedals fail you’d repair them rather then buying them again.
    So I am attempting to end the effects of another user-fooling policy by showing you quickly below, how to put new footswitches into your Ditto x2. The procedure works with the small Ditto and the x4, too.

    The usual note: You do this at your own risk and will probably void existing warranty. You could
    • put soft fabric under board, when placing on hard/edged surfaces.
    • don’t touch board components with hot or magnetic things.
    • use decent soldering iron with small tip.

    - solder + soldering iron.
    - standard screwdriver with large tip (no crossed slots) removing nuts around the top of the footswitches. Turn nuts to the left.
    - a torx 10 hexagonal screwdriver removing torx screws of bottom plate (4 in corners) and inside (1 in center, put back in to stabilize board when soldering).
    - rear side audio plugs need to loose nuts and washers as well.
    - two momentary replacement switches, non latching, normally off, and fitting an M12 or 15/32 UNS thread. Important: The diameter of their bottom part must not exceed the diameter of the through hole in the pedal case by more than a millimeter, otherwise they’ll not find enough available space inside.

    Repair time approx. 10-15 mins.

    I am using Lehle Switch Buttons as replacements.
    They are expensive, however prewired, hopefully sturdy and most importantly fit into the limited space underneath. Some Arcade buttons can work, too.
    Reverse order of nuts on Lehle switches, leaving the hexagonal nut on switch before inserting, later tightening with the round nut from inside.

    No further adjustments or metal work necessary.
    My soldering skills are less than mediocre, so i am happy that original TC buttons on board may stay in place.
    See end of article for more resources.


    Open pedal with soldered new switches. Polarity doesn’t matter.
    Please don’t mind my nonexistent soldering skills ;)


    Electricity-insulating tape on solder points should keep cables in place to relieve stress, when device is moved oftenly.
