One Knob fuzz: ALL the variants ultimate thread

[Plexi]

Too much happiness on one knob


Almost a Fuzz Face / Vox '66 ToneBender with a lot of variations, that finish the eternal suffering of the useless "fuzz" knob

- D*A*M Meathead, Dark Meathead, Meathead Deluxe (not one knob)
- Colorsound One-knob fuzz
- Black Arts Toneworks Ritual fuzz
- Emanating Fist 'Black Dust and 'Black Acid (not one knob)

There's a wonderful file with a great data/schem/layout:

My favorite:
Meathead, with 2n2222 at Q1 and BC109 at Q2, 4n7 at C1

Any experience here with Black Dust/Dirt?

I find getting the voltages "right" helps with one knob fuzzes

So I'm going to do a one knob fuzz, but get excited with all these variations of the same schematic.
Just thinking about possibilities of putting them all in one pedal, with the ability to switch between fuzz styles.... but I guess that would make it more than one knob.
Anyone done this?

Scratch that idea.
I had "fun" with this over the past few days. (I got some great constructive criticism of my perfboard soldering skills on the unofficial FB page).
After socketing everything, I realised it's still easier to mess around with different values on a breadboard.

Due to not having the same components listed in the variants, I messed about and now have a fuzz of my own (running through BC547/BC550 transistors) ! I just need to work on the enclosure.
