Hi Alan, it is more of a hum sound and it is basicaly present when pedal is static throughout the spectrum specified as well as whensweeping through the range.
I suspect that it is not so much the pedal, but how the next thing in the chain is responding to the impedance. I've played some amps and pedals that would hum a bit when the guitar's volume was turned down (you'll probably get that too). I'm not sure what the fix would be.
