Can you get a Tube Screamer sound using the right level settings of clean and
distorted signals in a mixer?

Does the Ibanez Tube Screamer TS-9 overdrive pedal mix clean and distorted

Keen's description of TS-9 clipping
The Boss Line Selector pedal can easily mix clean signal and distortion.
Favorable user comments about Matchless HotBox overdrive - (2 12AX7 tubes) - includes description of a mod done by Matchless to mix clean signal with overdriven signal.

You two seem to disagree. "The entire signal goes through the clipper" yet
"you'll still have unity gain clean signal from the opamp".
It sounds like perfectly clean guitar coming out of the Tube Screamer, with a
fainter standard full-distortion sound mixed in. This approach makes sense, to
get natural attack tone combined with distortion-type sustain. This could be
an example of an effect that produces a mediocre tone on its own, but sounds
great when used before a hard-driven tube amp. There is a great difference
between raw preamp tone and the finished Tone after the speaker. Vintage
effects were *made* to go before a tube amp, rather than being listened to
directly. You're not hearing the full potential of the effect unless you drive
a tube amp into the warp zone with it.
Mixing a clean and distorted signal in an overdrive pedal
makes so much sense, to get natural attack tone
combined with distortion-type sustain.

[I'm not sure who wrote the above.]
The Tube Screamer had a better mix than that unit. The fact that that unit
poorly implemented the approach doesn't prove the approach to be bad.
Can't you tap the signal in the Tube Screamer to hear a clean and distorted
signal simply being mixed?
This would be just the sort of weird, terrible-sounding preamp device that tube

A loud tube amp and speaker transforms the input signal in a complex way. You
have to do a mental transformation when listening directly to an effect,
imagining what it would sound like through a loud tube amp. Beginners might
well dismiss overdrive pedals in general, because they sound wimpy and staticky
when listened to directly. Overdrive pedals are not designed to produce an
overdrive tone in themselves. The sound coming out of the overdrive pedal is
not itself the overdriven sound. It's a misunderstanding thinking that the
sound of an effects pedal in isolation is the final sound that the designer
intended. Effects pedals, particularly 70s vintage pedals, are meant to be
heard as part of a tube amp rig. The purpose of the overdrive pedal is not to
sound great in itself, but to drive a tube amp harder than the amp can be
driven by its internal preamp.
When I listen to an effect by itself, I don't think "this sounds great", but
"this *would* sound great when combined with a loud tube amp". This applies to
the overdrive pedal especially. The Tube Screamer sounds bad by itself -- but
it was not designed to be used as an isolated piece of gear between the guitar
and mixer. Overdrives are specifically meant to be combined with a loud tube
amp, and if a buyer wants to understand how to get the tone the designer
intended, they must understand that the designer intended the pedal to be put
before an amp. If the buyer doesn't realize this, and is surprised by how bad
an isolated overdrive pedal sounds, the buyer's limited knowledge about the
intended configuration will probably prevent them from getting the best, most
musical and flowing tone using the overdrive pedal. The buyer will probably
conclude that all the enthusiasm over the overdrive pedal is unwarranted. You
will certainly not soud like SRV by running your guitar through a Tube Screamer
and into the mixer. If that's what you are trying to accomplish, you would be
very confused and disappointed. Some guidance about the intended and
recommended setup would be very helpful.
To get the most out of your equipment, you must both understand its intended
purpose, as well as knowing alternative, innovative applications of the
equipment. I've done some very successful misusing of guitar equipment, such
as putting a tube amp, speaker, and mic in the "effects loop" of a guitar
