The Italian (Jen) made VOX V846 wah wah pedals have been unquestionably the benchmark pedals for generations of guitarreros. Though components like inductors, transistors and caps changed over the course of production the specific sound of the V846 hadn't been affected too much. My 1972, 1973 and 1976 pedals on this page are within a (felt) tonal corridor of >95% of similarity.

This Italian made 1973 VOX V486 sounds just killer, with two CDIL BC109B transistors (silver can), a red Fasel inductor, tropical fish caps and an ICAR taper 100 kΩ pot.

This is an Italian made 1976 version with TDK inductor, FBC 318B and MBC 239C transistors, Centralab pot (code 1347609) and a pretty random set of caps with just one tropical fish cap.

This is another 1976 version with TDK inductor, FBC 318B and MBC 239C transistors, Centralab pot (code 1347609) and amore consistent set of caps than the version above.
