When exactly does it crackle just when you switch it on and off or in general when you’re playing through it turning pots etc

There are many things that can make it crackle from cables to jacks power supplies etc bad connections on pots dry solder joints faulty components and so on

You can do the wiggle test to try to locate exactly where it’s coming from use a pencil or something non conductive and gently tap on the components and wires to locate the source and hopefully rectify it

You can test your LED in place using a 3v coin cell battery just slide it in between the legs + to the middle pin and – to the outer pins to see if it illuminates if it was working prior to putting it in your enclosure make sure the pins aren’t touching any bare metal parts
