    I found a EHX Micro Synth pedal under our drummer’s drum riser. It was abandoned by a former inhabitant of the practice space since it is in a “broken” state. It’s got all but one slider snapped off and the on/off switch is lossey-goosey (if you shake the pedal left to right the switch moves accordingly). As I am playing bass in another project I’d like to be able to get this pedal working again. So I have a few questions I’m hoping that the forum can help me with:

    -Can I buy replacement sliders (the upside down T-shaped item you physically move)? I’d be interested to find out even if this means removing the entire part from the PC board if that part is available? The part number is 442NA4H104CDN 9915. Naturally I’ll need 10 of them (or at least 9).

    -I read that the power input should not be daisy-chained via one-spot pedal chains. As of now Guitar Center does not a functioning power supply that will fit in the hole. The closest thing was the adapter for the Line 6 pedals which have a smaller barrel, but it would not power up completely (might be an issue with the on/off switch). Can I buy a replacement 2.1mm power jack (ala Boss) and rewire it for that plug with no issues? Boss power supplies are easier to find than a vintage EH power supply (the GC guy that the new EH pedal use the standard boss pedal barrel power supplies).

    -The off switch is useless in its current state. I read these switches are the same as the Fender Jazzmaster switches. Is this right?

    If anyone knows any websites that sell these parts let me know. I saw a few on Ebay and it’ll be a $10 investment for the on/off switch and power plug. Can’t find didley on the sliders. I may just gorilla glue pickguard material vertically if the other two parts work and there’s no replacement parts in sight. Ideally I’d like to get this as close to original condition internally.

    Thanks–

    FYI the electronics aren’t screwed in as I was preparing to take the following photo.

    Yes you can get them from new sensor: http://www.newsensor.com/

    They have the white caps for the pots too, on the same page.
    The slider switch is this one http://www.smallbearelec.com/Detail.bok?no=37

    Do not use a Boss power supply either. You want a 24v supply, available from Musician’s friend. If you search for electro harmonix you can find them.

    Couple thing worth nothing.
    1. They have $50 minimum from that site. I Called and finally got them to sell me just the one 1 fader I needed but it took some doing.
    2. The fader they sent is not even a close match to the orignal. Wrong pinning, height…everything. Its in no way a suitable replacement.
    3. The fader cap looks great…now if I just had a fader to put it on.

    I realize this is an old thread but I’m in the same predicament. You wouldn’t happen to still have that old slider pot for your Micro Synth would you? I know you said it was the wrong part but it’s the right one for my needs. I’d be happy to buy it.

    I’m looking for the same 100k slider pot. The link that Liberty Belle posted didn’t work because I don’t think they sell that slider potentiometer anymore. Can someone please help me find where to buy the correct pot? Thank you

    Looks like its been a long time since anyone has posted on this thread but I found a link that may interest anyone with this issue.
    Heres a link I came up with…

    http://www.digikey.ca/product-search/en/potentiometers-variable-resistors/slide-potentiometers/262243

    Lots of slide pots available on the site. I dont know if they have a $ minimum for shipping like that old old link above.

    Im deterred from buying Graphic Fuzz or Pog 1s with broken sliders even thought the price is really decent.
    It would be nice to find out if this is not such a tricky fix.
