Jensen and Lelhe both have good transformers
If you are stateside, aplified parts has the Lelhe ISO transformer for a good price on reverb

Ok i think i got it now haha 
I double checked with the radial block diagram, that's pretty much the same i did, but i added the 10k and 1nf as per the schematic, hope it's correct now lol what you think?
Oh yeah i saw the lehle stuff but it's way too expensive for what i'm trying to achieve. Maybe i'll try them in the future... For now i just really like if i can make this work lol

Hm.. where do they join ?
Are you sure? i overlayed it in photoshop while tracing it, and checked it 3 times with the radial diagram and i can't find any differences...

No worries, thanks for the help
I'm making a pcb now, let me know if anything else comes to your mind, i'll order it in the next few days, i can't wait to try it out

Did you breadboard it before making the PCB?No worries, thanks for the help

No, why?
I breadboard half of the stuff i want to make as a pcb but... most of the time breadboard pick up noise and weird stuff or the cables loose connexion and i have to be extra careful so now i just use a simluation falstad as much as i can and then make 5 pcs pcb at jlc for like 5$ shipped it's not too bad... then i can mod it or lift traces on the pcb as needed until i make another new pcb with the fixes....
Did you spot something wrong from what i posted here in the last post?

I didn’t spot anything but I didn’t look very hard. I would breadboard and triple check any circuit I was making a PCB for tho!

Ok, well i'll see how it goes, i'm starting to hate breadboarding... I used to do it a lot but i ended up spending more time trying to figure out what goes where and why there's noise or weird issues... having to check every cable i use and not move it around too much in fear of something falling off the breadboard... lolI didn’t spot anything but I didn’t look very hard.

Oh yes for sure, i have quite a few to read suggested to me since the past days.
I really don't mind ordering 5 pcs pcb's to try and see if i made errors or even space issues with component size, and while i wait for the order i will read thoses.

If you connect the Ring contact of the jack to the ground your sleeve will always be connected to the ground through an inserted mono jack connector.
Thats not how I understand it. If you have a series of devices connected together there is a possibility of creating a huge coil (loop) via ground. This coil can picks up all kinds of signal.
But a potential difference can hurt if your lips touch the microphone and create the ground loop. So groundlifting scares me. Please correct me if am wrong.

Ground is still established with the guitar. It's only the split signal from transformer that is isolated. It receives ground from the next device.
DIs work this way. Ground from the console.
If your guitar amp and pedals are going to one circuit and FOH is on another circuit, you'll have a ground loop all the way back to the panel box.
