Engorged Gherkin Fuzz

This was going to be called the Ultra-mega Overly Engorged Gherkin, but that's a bit of a mouthful.

This is based on Mk II of a very popular, highly tweakable Big Muff™ derivative. One problem with the original is a couple of silly little 6mm pot shafts for a couple of the controls, making precise adjustment a pain. Second problem is another two of the controls are internal trimmers. Not much of a control.... So we've been thinking outside the box and put everything outside the box.

Seven - yes, seven! - controls on a Big Muff™. None of them are superficial either. As well as your normal Volume, Sustain and Filter we have:

  • Clip - blends between two different sets of clipping diodes on the second gain stage, which has a very noticeable outcome on the nature of the fuzz
  • Voice - adjusts the intensity of the scoop control, from mild to major mids cut.
  • Scoop - hey, we're in Big Muff™ land - you know what this does.
  • Crunch - adjusts how much clipping goes on in the third gain stage, doing exactly what it says - adding a crunch element to the smooth fuzz.

All in all, well worth the extra pedalboard estate for the 1590BB box this kit requires.

Kit is supplied with the MPQ3904 quad BJT chip (while stocks last) found in the original unit, but you can use four transistors instead if you prefer.

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. Tightest pot spacing is 20mm.

I was about to build a Pi clone when... 5 product stars
"I saw this with its extra Knobs, and had to try it! Wanted a heap of control over my sound and this thing delivered, I have it set with a nice crackly but soft fuzz which, if I kick my compressor, transforms into a rough and crunchy tone. Takes a bit of research and testing to figure out what the controls do but intuitive enough that you can get a good starting point for the sound you are looking for, just keep notes and experiment!"
