Unfortunately I can't show you the G3 anymore as it's long gone.
But for comparisons sake: There's a fullblown headphone amp. Stereo input, 4 x HP out, all with their individual volume controls (hence separate amplification). Goes for €13.30. In the light of that price, anyone telling me a passive aux in would *not* be pennies has got to be joking.

But unless you can Thanos-snap your fingers and have it magically connect to the board, case and the rest of the design, the unit price of a 1/4" jack is irrelevant.
That line of thinking leads straight into Tony Mckenieisms such as "what do you mean unit XYZ costs $1000?! these DSP chips are $25 a pop!"

So, what does it take in addition? Some minimal circuit (no idea what is involved, but it looked like pretty much nothing in the G3), some space on the PCB and another hole in the case. Done. If you design the entire thing to have an aux in, the 1/4" jack plus maybe some resistors (or whatever) is in fact all the cost this adds. This is not a complexed circuit and it doesn't need to be integrated in any kinda digital environment. Zero work involved but finding a place for it.
Fwiw, I'm not even saying the PE *must* have an analog aux in. These days, hardly any smartphones have analog HP outs anymore, so you'd likely use USB to feed audio into the PE anyway. But telling me a passive aux in would cost more than pennies (even with all possible "development" costs considered) has got to be a joke.

Sure - if you skip the audio codec, associated circuitry and the capacity to digitally process/route that aux in, you're all but done.

Why would you need to deal with any of that for a passive aux in?

Passive aux-in? It's an input to a digital device.
Unless you mean... mixing in with the guitar input somehow? Because, yeah, you don't do that on any kind of serious consumer product.

No, it's not. It's just mixed with the signal of the headphone out.
See above. Worked a treat on the G3.

I don't even know if you understand the purpose of an aux in. It's there to let you jam with whatever you feed into it. No need to run it through any processing. Just mix it with the HP out.

I don't think you understand how headphone outs work then. TL;DR, they are (comparatively) high power, and low impedance - which is the the exact opposite of an audio level input. Hook the two together, and weird interactions are guaranteed to occur.
Sure, it might sort-of work, and not sound like shit. But again, this is not how consumer products are designed.

Defenitely not what happened on the G3. It just worked. As said, the guy soldered some stuff in, no idea what the circuit looked like, but IIRC, it was just a single resistor. Even worked with quite different signals.

Besides, all that is completely irrelevant. As said, there's full multi-out HP amps for less than 20 bucks. So heck, let's have 2 bucks of additional cost for an aux in when mass producing something. That's still peanuts.

And fwiw, the signal you usually send into an aux in typically *is* high power, low impedance. You obviously don't run an instrument straight into an aux in.
Anyhow, I'll rest my case, this is getting absurd.
