The difference in shielding everything with copper foil and quality parts with a screened output cable in normal everyday circumstances will not be apparent except the over screened guitar has attenuated treble and sounds worse.As noted on the Kinman site, it is important to note the difference between hum and noise. Kinmans are not noiseless pickups, they are hum-free pickups. Humbucker pickups also are hum-free, but no conventional magnetic pickup is noiseless. Calling a magnetic pickup "noiseless" is a misnomer. You have to shield the guitar to minimize noise. Noise comes for RF that is pretty much anywhere there is electricity, so you will always get some noise. The goal is to minimize it. I have several Kinman sets and they are all pretty quiet, but the quietest "single coil" pickups I have ever used were Bill Lawrence pickups.
