Relay Bypass and (bi-color) LED Always On

Have you tried just using a regular LED? If your R100 is empty put the cathode facing R33 (R pad on the left)

I'll try that. Thank you ?

I'm getting voltage that fluctuates to the LFO. At peak it's about 4.2v and at minimum it's about .8v

Have you tried another LED? You’re getting enough Vf in order to illuminate the LED. Another issue might be with the switching.

If you replace it with a regular LED in the same spot, you’ll still get LFO rate indication.

Ok thanks. Hmm.
Unrelated, but I just tested the bi-color LED with my Peak Atlas and it definitely works in both green and red.

Also, Wouldn't just clipping one of the leads of the bi-color LED do the same thing as installing a regular LED?

I found a solution. I temporarily put a 500Ω trimpot in the R100 spot. Played around with the trim and found that green now lights up when active. Very dim at 500k and strong at the minimum, around 2Ω. I'll just solder in a 10Ω in R100 and call this finished.

On second thought, just a scrap lead for a solder bridge.
