Pure booster and gain relationship

Great question, I've also wondered about the exact differences between the Pure Booster and Gain Knob. I always use the Pure Booster in Pedal mode for adding Gain to Clean profiles, doesn't seem as dramatic an effect as the Gain knob but with a limited number of pedals at my disposal it fills the bill. This way I can use the same midi expression pedal to operate a Wah, Whammy and Pure Booster. I found the Pure Booster colors the tone much less than any other booster or distortion stomp I tried out but that's my ears opinion, nothing measured or fact related Anxiously looking forward to smarter, more scientific folks to chime in on this.....

My answer is not scientific but my understanding is that with the pure boost you drive the amp harder and thus get more gain as more signal is pumped into the amp.
Turning up the gain knob is more like increasing the Input sensitivity of the amp's preamp stage which to me is a slightly different thing, and to me it surely sounds different, too.

Of course, all this stands true if you put it in the Stomp section

Of course I'm talking of stomp box use of the boost here...

As far as I know, putting a pure booster in the pre stack section has the same effect of increasing/decreasing the gain of the amplifier, but I don't know the proportion.

Don't quite agree that PB is just a Gain .
I am using it a lot, almost in all of my new rigs , both in Pre stack section and locked in a X slot .
So, depending on rig it self and amount of existing stomps, PB will have different effect .
If it is about clean rig- it will just add Volume , some clarity, or better to say sharpness.
If I add the real Gain on clean profile- it will result in clean profile becoming crunchy or brownish , not clearer and sharper.

But if you add PB before overdrive or booster , it will add a gain , but only in Pre stack section .
In X slot section it will be just louder , no change in "gain " , gain will stays the same ....

At least this is what I hear when playing with PB.

Main use of PB in my case is to decrease impact of my pretty powerful Anderson pups , so I put and lock PB in B stomp , PB volume is minus something depending of rig , and than add PB in X slot , but plus something to help cutting the mix , and make it more articulative ,if you know what I mean ..
Just my 2 cents

ps
on the end PB has just one parameter- Volume , it may tell you something as well...

Without PB my rigs will never be so gooooood !!!
(it took me 3 years to realise power of this incredibly simple , bur gorgeous effect !
Thanks Kemper for that.

From the manual:

The Pure Booster features a “Volume” control like all the other effects, but that’s it. The Volume control will
boost or attenuate the signal without coloring the sound. When you place it in front of the amp or a distortion stomp, the pure booster has the same effect as the Gain or Drive control; placed after the Stack section, the Pure Booster becomes a simple volume control, with no further coloration of the signal.

Thank you, I stand corrected then.

We should believe to our ears much more ...
I can read Kemper Manuel as a starting reference , but my ears are the judge on the end.

No, actually it's your brain that's making up the final picture and is the judge in the end
From a physiological POV.

And my brain just got a lot clearer on the subject thanks for the info guys!!

Of course it is my brain , and my soul and my EAR in this case.
In opposite it will be somebody else , or very average Joe who believe in mainstream shit
In other words who is that entity telling me I am not me , ie I am wrong in what I like and what I do not like ????
