These drop-in boards are designed to fit the US-made Vox V847. They can also be fitted to Vox V848 Clyde McCoy, Dunlop Crybaby and Jimi Hendrix wahs with some wiring mods. These boards will not fit the Chinese-made Vox V847A, the mounting bosses and wiring connections differ from the US-made wahs.
My standard inductor is a hand-wound replica of the halo inductors found in early Vox wahs. I can also wind custom inductors on request e.g. Colorsound or grey JMI Vox wah specs.
Halo inductors were used in the first Italian-made Vox wahs, notably the Clyde McCoy. These inductors are only available on replacement boards or in wah rebuilds from me or Tom Lanik at North Star Audio. I no longer sell inductors separately, nor do not supply any other manufacturers.
