This project was provided by Eric Barbour of Svetlana Electron Devices. As opposed to the solid-state sound of all commercial wah pedals, Eric describes this unit as having a fat, buttery tone.

Eric was kind enough to send one of these devices to Chris Hurley for evaluation. After spending a bit of time, Chris comments: "In terms of Fuzz, this is quite a lively little beast. It can not only generate a thick fuzz internally, but also drive the front end of your existing amp into saturation as well. The Wah portion is interesting and can achieve numerous different sounds by varying the gain control. I'd like to see a seperate project based on the EF86 fuzz, since this device has a bit more mechanical construction than some might be accustomed to."
