PUE Sustain Filter
A great sounding Big Muff variant from Poland dating from the early 1980's. Original has a buffer stage after the tonestack and no volume control. I did a stock layout and a modified layout with a normal recovery stage and volume control. Can't find much information on the stock BC622 transistors but any medium high gain silicon works fine.
Stock with Mid switch
Modified circuit
