Wiring multiple Millenium Bypass switches together

One "last" question everyone,

For the board, I'll be using R.G.'s millenium 2 bypass that will be modified to switch 2 Red LEDs per FX. There will be 14 of these switches, all lined up at the bottom of my board.

For power: I can use any voltage that would be ideal, as I have not bought the transformer or built the power supply yet. Maybe a higher than 9v would be ideal? I was going to place the current limiting resistor for each LED on the MB2 pcb that i'll design.

Question: Can i simply run power/ground out of the power supply and daisy chain it across each of the bypass switches. So, each MB2 pcb will have 9v IN and 9v OUT. It is my understanding that this creates a parallel connection because on the PCB the in/out are connected and the switch just taps off that.

So, what I am trying to understand is if this will work, and what affect will turning a few switches on have on the rest of the chain? I know they need approx 3vs to operate so I cant be having it to where if i turn a few on at the beginning of the chain theres no jucie left to operate the others. Anyway, some help understanding this all would be wonderful! Also, what would happen if I wanted to dim the status LEDs? I would have to have minimum (for the circuit) and max (for the LEDs) voltage regulation, yes?

(and if you'r wondering this is comletely seperate from the illumination LEDs in my other thread)

as always, thanks!

I'm doing something similar, 3 pedals and a power supply in one box. I was told that I should decouple each circuit. My understanding of decoupling is basically separating them with a resistor coming off the power supply for each circuit (3 in my case) linked to capacitors at the 9v in of each board.

Edit: I don't think the bypass need to be decoupled. Check this thread out.
