ROG Whisker Biscuit
I thought a few Big Muff fans who were looking for something a little different may be interested in this. From the runoffgroove website: "The Whisker Biscuit is a hybrid of the Bazz Fuss and the Big Muff Pi. A single Bazz Fuss stage replaces the two clipping stages of the BMP. Smooth, super-long sustain, and good clean-up with the guitar volume knob make this circuit an interesting alternative to the standard BMP."
They suggest that for "a velvet-like reduced treble sound" you can add a 47pf cap (or choose a value to taste) in parallel with the 470k Base/Collector resistors in Q1 and Q3. Like you see in the Big Muff circuit.
