Yeah, I built the 2 ic's one.

Quad is not a good idea in the IC Big Muff. For a start, I don't like to use a quad when is not an exact double version of the needed IC, for examlpe: using a TL074 when the schematic asks for 2x Tl072 it's ok, but a TL074 instead 2x 4558 is not ok.

When I built the IC BMP, using the quad, I liked the results, but it was not the sound I was looking for, so used a layout with the two IC's, a 4558 and a 741, and the difference is HUGE. JRC 4558 gives more color to the sound than the TL072, and a 741 is a must in this circuit: harsh, noisy and really more suitable for a "fuzz like" circuit.

Sure, the IC Muff is a different animal but... it sounds too like a Big Muff, different sound,  somehow smoother, and great for rythm guitar.
