Anyone know what these are?

[sirbergersworth]

I was on JD's website the other day and noticed he had a new layout and kit for the D-Verb.
I have been wanting to build one of these for a while and so I ordered the kit. I usually just buy pcb's and source my own components but I just felt like building this soon and this would be the fastest way. Anuff back story. These little guys were in the kit and I cannot identify them.
Any idea? They both measure about 0.01 ohms.

They're just fancy jumpers.

That's just silly.
Now I feel very green. lol

Yup zero ohm 'resistors'. Or, as he says, jumpers

[jkokura]

That's why you get the 0.01 ohm reading... it's not actually resisting more than actual copper would resist. If you measure a length of resistor lead you'd probably get the same reading.

Funny thing is that there are traces connecting the thru holes where the jumper would go. Strange. I don't think I am gonna put them in, or should I? JD doesn't have jumpers on the pic of his build in the documents.

Btw, I got it all components minus the brick installed last night. I am painting the enclosure now.
Sometimes I feel lame buying kits but I have no problem supporting JD sometimes by putting some money in his pocket!

I hope I have no issues cause once I solder in the brick, almost all solder will be covered. I have done a check with magnifying glass and a jewelers screwdriver to make sure all the close pads are free.

Sorry, am I just having a brain fart and wondering who you mean when you say 'JD' and what website/project are you talking about? Should I know this, or do I and I'm just not thinking?

I think he is referring to JD Sleep at General Guitar Gadgets.

JD Sleep @ General Guitar Gadgets.
The pedal is his DVerb. Same as a Hermida Reverb.
New layout.

...

In the parts layout doc, it shows three jumpers that look like they need to be connected to me.

Are these the jumpers you are considering leaving off?

Yes.
On the board you can see a trace between the thru holes.
And, he only sent me two jumpers.
And his pic from his build instructions doesn't have jumpers.

I am gonna put jumpers in to be safe. I am just going to jumper them with a cut off lead. I am not using the 0 ohm resistor.

Did you consider measuring conductance between these pads with a DMM? Might save you some soldering/board clutter/frustration.... Or drop JD an email, and see what his response is.

I'd agree. If your DMM has a continuity setting, just test it. It looks like the board may have been moved to being double sided by putting in the jumpers as traces. It probably wouldn't hurt to have the extra paths, but it looks like a couple of those connect ground sections.

[sirbergersworth]

I did measure across them and there is continuity.
I did also send JD an email. Haven't heard back yet.

Yeah, I would guess you need no jumpers there. It looks like the layout was originally designed for single sided use, and it's been transformed into a double sided and those pads are now connected on the top layer.
