Yeah, a lot of noise in this pedal. The reason for that is because the enclosure was not grounded at all! Putting pressure on one of the switches would  ground it sometimes but it would make this crackling noise when done while playing. The jacks should ground it but because of the type of jacks and the finished enclosure this wasn’t the case. What I did was wire a jumper from ground on one of the boards to the side of one of the potentiometers. That connected the enclosure to ground and all noise went away. All of it!
