I saw this pop-up today at Macari’s and thought I’d check it out.  It’s a silicon fuzz face variant used as the fuzz board in one of the old Colorsound fuzz wahs – which is not completely unlike the Colorsound Fuzz Box one knob fuzz (which I used for the layout).

It’s a great sounding, if not somewhat standard fuzz face variant, but I think the magic here is the volume swell – which will be lost unless you uses a wah enclosure or plug in an expression pedal.

Here’s the thread on FSB that includes the schematic At first I thought it was wrong, and someone had a couple of resistors the wrong way around, but then I double checked a few photos, and it is indeed correct.
