Or if you have a TRS pedal, then join the ring to the sleeve in the cable, and that will make it a TS pedal. There are also adapters, and full on expression boxes that can covert to anything TS, CV, RTS etc https://ozinventions.com/enhancer/
I only know that coz I did some work experience there, they are not well known.
Thanks for sharing! I’ve been searching for a while for this exact solution. Much appreciated!
