Looper True Bypass, not so easy like it seems

[JackSkellington]

Hi, I'm looking some layout of the some DIY True Bypass Looper, one loope effects.
This is the basic schematic:


I found the Keeley one's gutshot:

It' includes a pair of extra resistors.
I'd say those resistors are between tip and sleeve of the jacks Send & Return. Pull Down Resistors, just in case we need of them?
Confirm, please?

And then I found some kits that includes a pair of caps (looking at the size I'd say 100nF). I can't imagine the purpose.

Help, please.

Thank you!

I've built multiple true bypass loopers based on the diagram you have there and they've all worked out great. The added resistors and such on the keeley aren't necessary. You'll be fine with the plain diagram. If you have some switch pops you can go in and add those pulldown resistors if you need to but you probably won't.

Thanks.
Actually, I already built a ABY looper, and with my DIY pedals it works fine.
I still want to know something more about those caps. I am just curious.

Since it's just a picture, and there's no schematic or build document, it's very hard to say. If the caps are there between the input and ground, that's much different than being inline with the circuit.

In any case, they're unnecessary.

Digging around on aliexpress's comments, apparently the caps aren't on the schematic included with purchase.

Keeley did that?  Spectacular wiring!!!

[JackSkellington]

Yeah, cool wiring!

Anyway, about those caps... It will remain a mystery?
