SOLVED LED Dimly Lit In Bypass

[Ginsly]

Are there any “most likely” reasons for this? I just put together a PPCB-style fuzz board (Fig Buster - thx @KR Sound!) and I’m having this problem. I did add a battery snap, and that’s how it’s powered. I also used a PPCB footswitch pcb.

Pedal seems to work normally other than the LED staying VERY dimly lit when in bypass. I repurposed an old enclosure and used off-board pots because of that. Also added some screw terminals, which I think over complicates things . No solder bridges that I can see…

I’m away but will add pics later- apologies. Just wanted to see if there were certain things to look at when this happens. Much appreciated!

Haha yep, I see now.

This is similar to what I was suspecting, except your LED was "grounding" to the INPUT rather than the OUTPUT. (In the latter case the volume control would control the LED brightness)

Ah! I see, that's actually really good to know for the future, too. Much appreciated as always, @Robert !

I'll mark this "solved" after @jwin615 helps me clear up my tangentially related issue about using these oddball 3pdt pcbs with your boards. It looks like my diagram isn't quite right, but I'm getting close!
