What are the R1 and R2 pins here?
So I'm recreating a guitar effect and I was looking for components on lcsc.com, and couldn't for the life of me find a jack that's just a tip and sleeve. The simplest thing I've found is this one. The datasheet says nothing about these pins. How do I connect those? And have you got any tips in general searching for components online?
