Varitone inductor
The original varitone circuit appeared in the Gibson ES355 Stereo in the early sixties. The value was 7 Henrys. The ones that everybody is using to make varitones are too low in inductance and the DCR is too high so they don't have the notch depth that the original Gibson circuit had. I'm an electronic engineer and had a company wind some custom for me a few years ago. I still have one or two left somewhere but I can't remember who the vendor was. I'm going to check with some of the makers of power torroids adn will post a source if I find one.
