Switch pedal with two loops.

[Buffalo Tom]

Hi. I wanna build a pedal where I can switch between two loops. Something like this: https://www.loop-master.com/cleandirty-effects-switcher153-vertical-layout-p-265.html. So I have a 4pdt switch that I'm gonna use. Please look at the attached drawing.. Im switching the unused send to ground. Is that correct or should I switch the unused return to ground instead? Cant switch them both becauce I need the forth pole for LED. Any help is appreciated! Thanks

That's fine.
