If I'm not mistaken, there's only an actual electrical connection on two of the pins. The other two just hold it in place.
Thanks - Yes, discovered it last night. THe PCB actually had two extra holes to fit the inductor perfectly. Like it was ment to be modded (or perhaps for another wah model)
Soundwise the red fasel has a smoother sweep and is clearer in sound.
I modded the circuit already to sound better so the improvement wasn't so noticeable compared to putting it in a stock crybaby (which sounds quite muddy in comparison tonewise).
