A genuine replica of the original Halo inductor made famous by the Clyde wah. Known for it's spongy quack and killer tone characteristic the Halo inductor has become an icon of wah tone. The Wilson Halo measures between 510mh-520mh and has that great tone Halos are known for. The Lead spacing is around 11.5mm. It may be neccesary to trim the feet off of the inductor if you are installing it in a Crybaby or Vox wah as their inductors tend to site a little more towards the rear of the wah limiting space. Feel free to message me with any questions.
