Some people prefer simplicity - less is more. Some like to tweak their knobs all night - this one's for you...
At its core this is a bubble font green Russian Big Muff but with a few tricks inside.
At the front of the circuit is a LPB pre-boost, enabling you to whack up the gain level and really push the fuzz circuit.
This Pre boost is complemented by the Focus pot which controls how much of the boosted frequency range gets through to the Fuzz.
The final extra control is a Mids pot, which does what you'd expect - shifts the midrange so you can tweak the tone to perfection. Not everyone likes the characteristic Muff mid scoop after all.
That's a lot of controls on the face of a 1590B, but it works well, and even the most sausage-fingered of you should manage with the right choice of knobs - keep them small! Pots are only 17.5mm apart.
Now the downside - the board requires a small hack. Careless capacitor placement on the schematic means one cap needs to be bodged in. It's really simple - don't sweat it - check out the main image.
If you go for the vertical-mount pots they have round shafts - take that into consideration when ordering knobs - you'll need set-screw fitting. They're highly recommended on this build.
