Here’s one for Syd Barrett era Pink Floyd fans. This is the pedal Syd used on tracks like “Interstellar Overdrive”. It’s more like a buzzy overdrive than a typical fuzz pedal.
I will probably build this with .15″ pitch stripboard but you can use .1″ pitch as well. The bottom strip is for mounting the board on standoffs but if you’re not using standoffs you can cut that row off.
This pedal is normally powered off a pair of AA batteries for the -3V. For daisy chaining you could use the inverter + regulator daughter board that Mark posted with his Maestro FZ-1 layout
Here’s the layout with the requested switchable gain boost mod
the requested layout with inverter and regulator onboard. This is unverified
