This is the most sexy and exciting board available here atm

I find that the noise reduction from isolated power is a lot more apparent than a ground loop. Ground loops not always occur, noise from non isolated power is much more common.

Pedalboard use. Parallel effects or effects chains.
Sure, it can be used to drive multiple amps, but with that caveat of ground loops.
One could add a ground lift on the pedal that lifts the sleeve contact. As long as the sleeve contact at the amp is correct, no harm done.
Fairly common in pro audio with the multitude of power sources and everything eventually went back to the desk anyhow.
But you also have a lot of transformers involved that typically handled most isolation issues with ease.

so basically use isolated jacks. Is there a situation where having the sleeve grounded here would be beneficial. I see plenty of builders that don’t ground their output in their pedals.

That should work, but it will leave the output somewhat floating and could be noisy.
I'll yank one off the prototype today and see how it behaves.
It's only ever an issue if the other end(amp) isn't grounded properly.
Can you suffer a fool for a couple of minutes while I work this out in my head? So the guitarist would have to split their signal to two effects pedals before this pedal so that they could feed the return of those effects into this to be mixed with the clean signal? Does that make sense?
Or alternatively, they could run a guitar signal and two other audio inputs and mix the three on the fly?
This pedal looks cool and I've been waiting patiently for a Signal Blender PCB for months now so I'm all in on the concept. But I'm having trouble figuring out how to use this. The signal blender uses a send and return so the clean guitar signal goes to the effects pedal before its returned to be mixed. This doesn't do that, right?
So two of these would get you to the OBNE Signal Blender, right? One splits the signal and sends it to other effects pedal and the other one acts as the return?

I don't have this pedal but do something similar with a mixer and pre amp that has a bunch of outputs. The splitter lets you do things like run dry signal separately to a reverb, modulation and delay. So you can have reverb on your dry signal but not your delay or you can run the effects separately into into an EQ or dirt pedal. This works best when the effects can be set to wet only. It also gives you finer control over the volume levels than the balance on the pedals themselves. I think some people also run the splitter to separate amps.Can you suffer a fool for a couple of minutes while I work this out in my head?

Alright, I'll wait.

Any update on an isolator that we can use with the splitter for running to multiple amps avoiding possible ground loops?
