This. But also the bootstrapping helps raise the input impedance as well I think.
I think he did this because you are limited to how high you can reasonably with BJTs.

I don’t mean to pull you into this feckin quagmire of a thread, but since you were so helpful with my Fuzz Buffer redesign and getting me to understand the characteristics of both common emitter and emitter follower buffers, can you shed some light the question from @cdwillis just above?

The "how can I make money building pedals" threads pop up sporadically in the forums, yes. In fact, in this thread was a comment about someone aghast at pedal profit margins.
I think you mistake my point. 29P was used as an example because it's the most recent interaction. My point is more that before we start throwing faeces, let's let designers vent their natural defensive reactions to being traced and have a decent interaction. Perhaps these snake oil vendors don't know the oil they're vending. Ain't nobody pouring their heart and soul into the community after feeling hurt by being traced AND having a bunch of white knights jumping on them screaming M'Lady on behalf of the pedal buying public. (There are a bunch of scumbags out there for sure, but the smell of shit lingering over time definitely shows).
We can shut the borders, or try to understand our fellow human.

Ref. the AC input resistance figure.

Sorry. I’m used to looking at those guitar science calcs, but did not realize they had a bootstrap version.
Thanks for the link!
Huh, gonna have to go back and look, didn't see such a comment and usually the sentiment round these parts is the opposite.
Particularly in those "how can I make money building pedals" threads, which are full of "you can't" replies.
Nah, I don't see any value in having "decent interaction"s with shitty people. As scientific tests have shown, and has been validated by my decades on this earth, the likelihood that somebody actually changes their mind when presented with new and conflicting information is near nil, so why waste time trying to change a douchebag's mind when it's just as productive and way more fun to make fun of them for being a douchebag.
Sufficiently advanced incompetence yadda yadda yadda. It's not and never will be an excuse.
Oh noes, a shitty designer may not feel welcome in an online space wherein his shitty design was exposed for its shittiness!
God I *wish* I had the kind of clout where I could chase dudes like him out of the industry. Never gonna happen in my lifetime though.
At this point in my life I understand my fellow human *just* fine (when you're a member of a marginalized group in a western society that devalues you for things you can't choose not to be, "understanding" your fellow human is a fucking survival skill - and it's *just* as good at sniffing out passive racism as it is at sniffing out douchebaggery in niche fields of interest like pedal building - it's the same sort of data, just with lower stakes).
That's why I'd rather call a douche a douche. I'm not doing competitive debate anymore, I don't owe anybody decorum or respect, and I harbor no illusion that you can somehow "respect" a douche into being a better person.

I agree with idea of comparison (I love this sort of utility pedal!), but my immediate thought is:
Having a single PCB locks you in to those 4 buffers — but what if I don't want a Klon buffer in my comparison and want an AMZ Super Buffer instead to compare with my Cornishish, BJT, MOSFET and JFET buffers?
Most buffer PCBs themselves are small enough that you could take a rotary with 4, 6 or even 12 channels and just load up whatever 4, 6 or 12 buffers you want to stuff in a box to compare. Okay, 12 Buffers will likely need a 1590BB, but I bet you could stuff up to 6 buffers on PCBs or scraps of Vero/Perf into 1 1590N1.
My personal problem is I now want to build the pedal you describe (albeit individual PCB/Perf for each buffer), even though I know...
I should just breadboard a buncha buffers.
Simmer down Keyboard Cowboy, lest newer forumites think you're a piano/organ/synth-playing keys-commando. Even though there's nothing wrong with keys through effects, still...
Kursk come, Kursk seared ...
I'd posit that having ink from a faulty pen could be just as hazardous as graphite-shavings, but not so much so as ...
S P A C E - M A D N E S S...

Group hug?
I mean with that many buffers, you might need like a *really* good power supply to power it all
Also don't forget to add the ADHD's buffer to your list! I think it has a *shockingly* high parts count for a buffer.

I'm thinking — skip the rotary and just have a master-bypass stomper and all the buffers on toggles, in series, with multiple flip-flop order switches between them...
ALL ON, which sounds better:
Klon buffer > AMZ Super Buffer > Cornish > BJT > MOSFET > JFET buffers?
or
JFET > MOSFET > BJT > Cornish > AMZ > Klon?
or
BJT > Klon > AMZ > FET > Cornish > ADHD...
?
A veritable buffet of buffers!

Is it a 3 ch splitter to match your 3 ch mixer?I have an idea.....
