Hello everyone! I have an H9 with Barn3 OX9 and I would like to connect an additional switch to it, exactly the same as the Tesla of this same brand. But I want to build it myself, mainly because the box I have is a bit smaller than Tesla’s, just enough to put it in the exact spot on the pedalboard. I know that it works with TS cable (mono jack) but I don’t know the circuit diagram (I imagine it will be super simple). Another possibility is if someone who has the Tesla bothers to open it up and take a picture of it.
