Hello Guys, In the past, I've used passive single coils on my teles. Before installing them, I shield all cavities with cooper foil . I finished my building my latest telecaster. I'm planning on installing a set of Greg Koch Fishman Fluence pickups. This is the first time I'm installing active noise cancelling single coils. Should I shield the cavities ? These pickups are hum free so I assume shielding is not required . Even so , before drilling screw holes and solder the whole thing together, I would like to know the experts' opinions on this matter. Thanks in advance!
