nope, the BOM doesn't say anything about positive ground.

Don't they normally use enclosed PCB mount jacks?

ok, I see... after looking at the build doc it looks like the dot (cathode) goes on top (not the bottom).

"The cream dot on the part denotes the cathode of the internal
LED on the optocoupler and should be placed as shown above"

Thank you. I've never once gotten an opto right on the first try.

I put the dot on the bottom where the doc says to, but it measures positive instead of negative and when I attach and LED to the legs, it doesn't light up.

Moved to VFE forum

it look very cool, sometimes the accidents are better than perfection, plus this one phases!

And really, isn't that what we're all after?

Yeah, you're not going to be able to hear the difference, but you can feel the mojo.

Are you talking about resistors?
Carbon comp are 5% tolerance, metal file are 1%. If nothing else it's closer to the correct value than than carbon.

Knew it had to be something simple.  Half the time those are the hardest to find because you're looking right at it.

I can't imagine what you're talking about......

Well, at least it'll cut back on extended family feuds erupting over dinner.

Yeah, but for those of us on the sidelines, that's entertainment.

That is correct. Installed the right way this time. Blew the led as soon as it switches on.

Is the clr a 4k7 and not a lower ohm like 4.7 ohm as an example. Is the clr circuit itself correct, you know that's a pretty simple power to clr to LED to ground.

Thanks guys, haven't gotten back to it yet, it is killing my OCD.

I drew a diagram of how the ground is wired just to make sure it was all fine and I think it should be. I had already wired both jacks to ground to eliminate that possibility.

I think I might make a audio probe with a cap and an old guitar cable and work backwards from the output lug of the switch.

I kind of think the problem is the switch, but who knows at this point. To many new variables to me, new iron, new solder, different wire (cheap) wire than the stuff at smallbear, and the fact that this is the first board I tried to design myself. come to think of it I should disconnect the ground from that and make sure that isn't were the problem is, though I was careful to run the checks in Eagle.

But if it were the stomp, I would think you would either have effected sound only or bypass only unless it's lug 8 with the issue. It would have to be defective, you'd still have one or the other. Have a look at that input jack.

That etch makes the pedal look like it's made of concrete, which is actually pretty cool. Paint it flat gray and fill the labels and tractor graphic in red. It will look great.

I'd love to k ow how to do that, got a tutorial. I can paint it, and fill it, but how do you do two colors?

Swapped ic out, put another one in. Same thing happened

You put it in the right way round and it did the same thing?
