    Hey, everyone. My beautiful Poly Chorus (got it sometime around 2000) isn’t working properly (obviously). The clean signal goes through without a problem. However, when I hit the footswitch to activate it, sometimes it provides the effect and sometimes it doesn’t. I’m beginning to think it’s a problem with the footswitch but I’m no electronics expert.

    1. Do you have any insight on what the problems might be?

    2. If it is the footswitch, what kind do I need?

    3. Where can I find the user’s manual online??

    Thanks in advance!

    No effect when you hit the footswitch or does it kill the signal?
    Does it happen in all modes?
    Take off the back and post a photo of the inside, careful you don’t rip out the ground wire attached to the back plate.

    When I hit the footswitch to turn the effect on, sometimes it works but often it kills all the sound.

    To be more specific: when you hit the switch sometimes no sound will pass.
    When you do get signal through, is it only clean signal or are you getting affected signal?
    Does it do this in all modes?

    When I hit the switch and it works you hear the signal with the effect. Without using the switxh to tuen on the effect the clean/dry signal goes through just fine. just hit or miss if I switxh the effect on!

    I’m currently working on repairing one of these. Im finding a lot of the wires are kind of brittle. I’ve had two fall off while moving the board. You may want to try reflowing solder on the switch connections. If that doesn’t work I would remove the wires, strip back the plastic coating and resolder.
