    So, I'm in the midst of overhauling my crybaby pedal and I've hit a snag. Was trying to convert to true bypass like this...

    I'm using a 3PDT switch instead of a DPDT and I think that's the problem. How does the wiring change with a 3PDT? Thanks.

    Guess I should explain a little more. I wired the 3PDT just like the DPDT and left the middle row vacant. However, the pedal doesn't work at all now so I obviously goofed it up.

    Thanks. The article helps, but when the switch is a big square, how do you know which way is up? Meaning which pin on my switch is #1 and so on?

    Ahhh, I see. Sorry. Here's a link that should be more useful: http://stinkfoot.se/archives/546

    The last part if the article mentions how to orient the 3pdt switch.

    "Unlike a DPDT, which has a 3×2 layout, a 3PDT is uniform (3×3) so you have to know which way to turn it. To make it correspond with the diagrams above, turn it so the holes line up north-south (imagine being able to thread a needle through all three holes in a row – that’s one of the three switch sections)."

    Ironically, I just got a like new crybaby rev H and I think it sounds pretty bland so I think I'm gonna do the bypass mod (like you, with a 3pdt). What resources are you using for your overhaul? Seems there's sooooo many mods to pick from.

    I attached a pic that I made where the top is superimposed over the bottom. It helped me trace things and figure out the Cry Baby. Consider adding an output buffer- it helps restore the wah effect in front of a fuzz which would have loaded it down.

    Alright. I've bought the wrong switch twice now. Someone tell me exactly which DPDT switch to buy from Small Bear. I'll go put on my dunce cap now.

    Is this right? http://www.smallbearelec.com/servlet/Detail?no=24

    Says it's for bedroom gigging and prototyping. Is there a more robust switch?

    Try this. Note the orientation of the pins.

    If you want to buy a more rugged DPDT switch from Small Bear,this is probably the one.

    Carling switches have a good reputation and are also recommended by our friend Stinkfoot.
    If you still have the 3PDT switch you can use the schematic above,or just ignore the third row with the LED if you want to.
