Hey all. I'm working on a 2 in 1 build with 2 Special ODs. For the LED wiring can I wire it up like the following? I want a blue bypass LED to show the pedal is on and then the red and green will be for their respective PCBs. Not sure if this works or not. I removed the SW wire from the right PCB and have it going to the negative on the LED. Then the positive with a 4.7k to +9v Thanks!
 
I'm not getting why you'd want the cathode from the blue LED wired to each of the stomps.




Here's what I'd do:

The A/B stomper is good as you have it — ie I'd want to know which circuit will be active before actually engaging the pedal — so at least one of the channels will always be lit up, regardless if bypassed or not.

For the master bypass, I'd run its own separate CLR — which according to diagram in post #2 appears to be the case if the red squiggle above the blue LED is indeed a resistor.

What I see missing from the Post #2 diagram is a GND to the A/B stomper. Just run a ground from the right PCB and that should do it.

You should connect the Master Bypass's CLR to its anode, in case you accidentally ground out the LED past the CLR (if on the Kathode) you wont 'splode it.



This might be of interest to you — A OR B OR A>B TOGGLE.

Or ...

Dimming the Channel-LEDs when in bypass mode.
