Skreddy Pink Flesh

Here's the layout for another rare Skreddy effect, like the Mayo posted previously.  Info from the builder:

Based on the "triangle-knob" circa 1971 4-transistor fuzz, but I've changed the input capacitor to a more saturated-sounding type like the circa 1973 'rams head' version fuzz.

From there, I've tightened up the bass and smoothed out the highs and eliminated the mid scoop.  So instead of a raging wall of fuzz, you get a more focused and amp-like tone, without having to stack with eq's and/or other overdrive pedals to smooth things out or bring up the midrange.

The Mayo had scooped mids, whereas the Pink Flesh has switchable flat and boosted (juicy) mids.  Using these layouts, the Pink Flesh and Mayo will have more in common with each other if you've used the mids switch shown which will give you a greater variety of mid levels for each pedal.  There is still enough of a difference to make it worth having both though!

Update: Some values have been corrected in the layout below after looking at the values in my original.  If anyone has built this from the previous layout this summarises the changes:

• 220n cap to Q2 base should be 100n
• 220n cap from Q2 collector to following stage should be 100n (Tropical Fish)
• 100n cap from Tone 2 to Q4 base should be 47n (Greenie)
• 68n output cap should be 100n.

The change in output cap means that a 4PDT switch for Pink Flesh/Mayo modes would now not be required and you could just switch the input caps using a DPDT switch.

Pink Flesh / Mayo switch:

This may not cover all the differences between the Mayo and Pink Flesh because Marc tuned each one by ear to remove fizz and so they could all be almost bespoke, but it'll get you in the right ball park with both and certainly close enough to please most people.  If you do get some fizz, just swap the 470p caps to smooth it out, and/or experiment with different transistors until your happy with both circuits.
