[sdiy] Jim Dunlop Cry Baby Wah-Wah.. 500mH inductor replacement .. Found a small professional MuMetal shielded matching transformer @ 530mH on primary..

[Mr&MrsAccount]

You can try the mu-metal shield but I bet it will play havoc with the inductor value, so the end result might be unpredictable. 
  
I think emulating the potentiometer will be harder than fixing the inductor hum issue. A real pot will allow almost any signal level with no distortion. 
  
I'd fix the power supplies that make the noise rather than try to shield the inductor.
