Custom drop-in replacement for the fret PCB for Guitar Hero controllers using Kailh Choc Mini switches. Please check the license before use.
This should fit all guitars, I hope? You need a washer probably for some guitars.
LEDs are SK9822-ec20. You need to cut a bit of plastic off the switches case but its not completely horible and only takes 2 snips.
Side note: I actually havent ordered PCBs for this but i have test fitted it with a 3d printed one and it seems to work fine.
