Hi everyone! Very frustrating there's no better solution other than not to use Latching relays. I'm in precisely the same boat with THREE VFE SPS circuits... I'll spare everyone my troubleshooting essay and summarize by saying the latching relay is not seeing voltage on pin1 and so it never switches. But when engaged the LEDs light and the 3 pedals sound great. I'll buy some non-latching relays OR add a traditional stomp switch.
Be well!
