So a client brought me this to 'fix' for him. the 2019 Les Paul Standard. It's actually very pretty to look at and it plays pretty darn nice. His problem was the sound. No matter which of the 500 different combinations he tried, he wasn't in love with any of it, it was like there was some active tone sucking going on.. he just wanted it to sound like a Les Paul Standard. I'll admit I'm not a huge fan of these passive electronics doing 100 things. Active versions work so much better in my opinion but the client wanted to go back to basics. It did sound dull, especially the neck pickup. I recommended going to regular style CTS 500K pots. .022 Orange drops and Gibson 57 Classic and 57 Classic + pickups. First thing I noticed? Every hex nut on this guitar was finger-tight. Including the tuners. I didn't need any tools to release the offending circuit board. And here it is with the new pickups, they are nickel instead of the original chrome but it doesn't detract in my view. It now sounds GREAT. Client was over the moon... sometimes simpler is better.
Maybe those LEDs were for a passive clipping circuit. I guess that could work with hot enough pickups, but ... yuck ....
Great job and a sweet top on that guitar! Shame it needed all that work to make it sound like a..... Les Paul
