ODR-1 + TS dual pedal

[gKorg]

Hi guys.
I never had a TS (!) nor a ODR-1 so i decided to make a dual pedal with both of them and a A>B/B>A switch . I never did dual pedals and i'm quite ignorant so i wasn't really sure about many things.
Here is schematic:

I did one mistake: i built it before breadboarding it. I usually breadboard everything but It was too big and i was too lazy... (i am still waiting some components so i couldn't complete it yet but i'm 90% done)

There are a couple of things i'm not sure:
1) i made two separated VB. I imagine i could have used just one but i wanted to keep the two pedals completely separated while only sharing 9v. Is there any drawback in doing like i did?
2) Do you think there is anything that could cause a problem somewhere else?
3) I build the TS with the bass switch mod, as shown in the schematic. Now, thinking about it, i would have maybe preferred a knob. I tried to understand which alternative would work better but i'm not sure. Can you help me with that? I have 3 versions:
1: 2: 3:
Thank you for your help guys

Edit: i realised i drew a wrong connection for the LEDs. Of course there is a RLED before each LED, not a shared one

One thing that happened to me, flipper switches on gain pedals could oscillate if you wire the flipper like that. I would physically route the wires further apart. Maybe around the outside of the switch. Just a thought.

Thank you jimilee, i am always surprised about things like this one. I would have never thought. I will keep it in mind when i'll finish the build. Thank you!
