Keyboard pedal broken

    Hi, this is for anyone who knows anything about electronics and/or keyboards.

    The sustain pedal of my Korg Concert EC 350 is broken.

    http://www.alltime.su/obj/img/piano/large/EC-350DR.jpg

    it got damaged while i was moving it, I stepped on the wire that connects into the pedal and it got ripped out off the pedal circuitry. I got someone to solder it back together again but it still wouldn't work.

    I looked around a few places and I can't find anyone who wants to take the keyboard into their shop to repair it, and I'm looking for someone who might be able to fix the pedal on its own.

    BUT in the meantime I was messing around with it and I found that if i touch 2 of the 4 wires that go into the pedal together, I can get the sustain to work. It works like a simple "normally open" switch. so I was thinking could I abandon the circuit board altogether (as it has functions for three pedals and I only use one) and just wire up a simple "normally open" foot switch, this would work as I know from touching the wires, but would I risk damaging the keyboard? Or myself?

    Thanks

    You've got it right I reckon or at least the majority of sustain pedals are just non latching normally open switches.

    I'm sure there's someone around here who could get the old one working again....

    yup.

    my son has a keyboard in his bedroom and I rigged him a sustain pedal for it with a simple non latching foot switch.

    Thanks for the help. I might chance it so, it's just that the resistors and the circuitry on the original pedal made me think that it's not so simple...It's not the same input as a simple jack pedal, it has a 4 pin jwt connector.

    The fact that it worked when I touched the 2 wires together has me fairly convinced though.

    The resistors and that could be for the other pedal functions you mentioned above.
