For Fuzz Friday here's the newer and highly tweak-able Swollen Pickle from Way Huge. Like the Mk 1, originals use a MPQ3904 transistor array instead of individual transistors. Couldn't make that work this time around, so just stick with individual 2N3904s. Originals also have 2 of the controls internally, but what's the fun in that? All 7 pots are for external mounting and the whole thing will fit in a 1590BB with top mounted jacks fairly easily. Here's the schematic for reference. You'll notice a few values are a 10th of typical values found in a Big Muff (indicated by an * in the layout below). Not sure if it's a typo on the schematic or just the way Way Huge did it this time around. YMMV
