A japanese boutique Big Muff variant with some bell and whistles. The 1979 switch adds a different stexture and aggression to the distortion. Doping switch is basically and Mid/Scoop tonestack switch. And the Mode switch (which is an internal DIP switch in stock units) toggles between two values for both clipping caps which adds some bass i one postirion. The 33k and 24k series resistors are replaced by one 56k resistor due to lack of space on the board.
Schematic is avaiable HERE.
Those 100NF + 10NF in parallel is a strange choise. I really don't think that adding 10nf will change anything to the sound.
ReplyDeleteSounds nice anyway !
had to swap tone 1 and 3 to get the the sweep orientation right (at least according to the videos i watched) but everything seems to be working. very sweet muff variant. thanks for the layout, anders!
ReplyDeletebtw this first version of the layout is correct per the schematic, but the tone was definitely reversed as it was. so maybe it's a typo on the schem?
DeleteI built one on a pedalpcb. But I have to say this is my new favorite muff
