Looks great. I bought both the plate (which i had to file out to fit right) and the 4-way jack. I get some kind of hum when using the 4-way with an input (even after severing the jumper). I've given up trying to debug.View attachment 3049464 I didn’t use the 4 way jack as you have to modify it. So this is the route I went.
Can I ask, did you remove the grounding washer from the locking jacks you have there? I'm thinking of just ordering those from redco and saving my solder-able ones for a different project.
