A 1994 V7 Green Russian Big Muff Pi with tone switch and 2N5089 transistors. Built for Maarten, bass player of Ride The Fader and Nova Sky. Got the tone switch from Guitar FX Layouts, used a SPDT instead of a DPDT. Tapped the leg of C10 that is connected to C9, connected it to the middle leg of the SPDT, soldered the 4n7 and 10n to the other two legs, twisted them together, soldered a wire to it and connected the wire to leg 3 of the tone pot.
