BE: Fuzz Buffer

Not that anyone is likely to, but please don't rush out to build this - it's a concept that should work, but I have not tested it yet.  Might need some fine-tuning.

It's a combination of the AMZ pickup simulator and a Pete Cornish buffer - so basically a fuzz buffer to drop in front of anything that does not like being behind other pedals.  Typically a fuzz face.

I have a few transformer options to experiment with, so see how that works out.  Switching might be interesting, as I think a loop would be good here.  i.e.  switch the fuzz on/off via the buffer.

A PNP buffer can be done by inverting the power supply and using a PNP transistor (works on LTspice).  This might be handy for building into PNP fuzz, with needing an inverter.

This is similar in function to the Aion FX Proteus, which uses a 42TL019 transformer.  

Pete Cornish Buffered Bypass - Offboard wiring

A 3DPT or a 2DPT switch can be used for this.  Pete Cornish uses a 3DPT, perhaps because he solders the LED circuit to the switch pins - who knows...

I added secondary power filtering on the buffer, which of course, can be easily removed if you already have it on the effect circuit.

Stating the obvious:  when using switched jacks, it's very important to ensure you are wiring to the correct side, or this will not work.

PETE CORNISH: Buffer

Just a little Cornish buffer that I use for buffered bypass / Pete Cornish builds.  It's small enough to sneak in at the bottom of an enclosure below the foot switch or standing upright against the side.

I sometimes add an extra row for additional power filtering - for the circuit that it's buffering, and there's still just enough room to fit a LED resistor on the board (will need an extra cut, and maybe relocate the diode - I'm sure you will work it out).  

I guess the first question might be, why bother?  That's big for a buffer and there are other smaller layouts - true.  It's only five columns longer than the one on Guitar FX layouts, so it's not huge by comparison.   It happened to suit something I was making, so why not?

The classic Pete Cornish buffer - some deride it, others love it.  Which pretty much describes every pedal Pete Cornish ever made.  

Great to use for buffered switching, AKA not true bypass.  Which is heresy for some but makes perfect sense to others.
