The V846 Wah-Wah was initially manufactured in early 1967 by Thomas Organ in Sepulveda CA. By mid 1967, production was moved to EME (Eko guitars) in Recanati, Italy. About a year later it was again shifted to JEN of Pescara, Italy. By the early seventies, production was divided between JEN and Thomas Organ in California. By the late seventies, the Thomas facility in CA was shut down. V846 production was then split between JEN and the Thomas International Corporation facility in Chicago, IL.

Tonal Differences Within V846 Wah Production
Despite the fact that all , V846, and pedals were constructed from the same schematic, significant tonal differences may be heard between pedals. While any of the components used to construct the pedal may affect performance, two parts are responsible for most tonal differences: the 500mH ferrite core inductor and the 100kΩ control pot. Let's take a look at how these parts affect the tone of a wah pedal.
