Adding LFO LED to the XC Phase?

Hi all,

I'm looking to add a LFO LED to the XC Phase. Would this be possible? I wanted to do an bright white or UV LED. My sister-in-law painted this enclosure for me. It would be a shame not to have Navi glowing with the rate...

Resurrecting this old thread because I was curious of this myself. I found this thread https://www.diystompboxes.com/smfforum/index.php?topic=110664.0 and it has this neat pic that I believe has been verified.

This appears to be the spot on the PPCB XC Phase going inbetween the negative of C8 and pin 6 of IC3

I could totally be wrong, but would anyone care to double check me? I'm going to be building one soon so I can try then.
 
this method will work but it's taking the square wave output of the op amp so the LED will only blink in time with the rate, it will not swell or throb or ramp the way the LFO's triangle wave output does
