Vita Fuzz

Fuzz Face derivate with a Big Muff style tonestack manufactured in Riga, Latvia in the late 70's. Originals has a foot controlled treadle which adjusting volume. I subbed 30k resistor connecting to collector of Q2 with a 50k trimpot for fine tuning bias.

Spektr 1 Fuzz Wah sans LFO

Lot's of love for old soviet circuits here lately, find it very interesting since sometimes the designers started from scratch with no input from the oustide world resulting in some quite unique designs. 

Here is a gnarly beast, Spektr -1  fuzz Wah. I omitted the LFO section connecting to Wah circuit since it needs a seaparate battery. It calls for quite a few PNP Germaniums which is still cheap and widely avaiable. Still not sure about the D814 zener diodes. Voltage rating varies between 7v and 11v depending on its suffix which isn't marked on the schematic.

I also moved two of the internal trimpots which controls volume output to panel mounted pots.

Currently unverified.
