Anyone have experience taking advantage of the "Low-End Trick" of a TubeTech PE1C?   I have the Softube plugin and it's discussed some, but since I am unsure as to how or why it works, I'd be curious as to how some of you may have used it, opinions, practical explanations, etc.

There is no "trick".

It is not a "life hack" .

It is not "disrupting the mixing industry", either.

On a Pultec™ EQP-1a the Low Frequency "boost" is a shelving filter.  The "cut"  acts as a peaking filter if you turn them both up, you will get a boosted LF range and an attenuated low midrange.

Here is what that looks like when you set the LF to 100Hz:

What is it then--a "magic bullet"?  A "secret weapon"?  A "miracle cure"?  Sorry... I couldn't resist.

several EQs do this now...the massive passive for example, and GML
with the shelf switch in, the bandwith knob controls the dip right before the boost (or boost, right before the cut.

there are several uses for this...like any other 'not a trick'. it's just a thing.
if you have to cut lows on a track, a small boost right before the cut can make
the results sound less thin, for example.
likewise a boosting low shelf can be cleaned up with a dip on the top of it.
similar thoughts on the high band.

i have often thought as far as passive EQs go, if there is any trick...
it is using inductors not gyrators, as gyrators don't seem to saturate.

but i am just another guy buyin' donuts...
YMMV...'cause you are on a different road.

The Focusrite EQ was like that as well, and caused SSL to implement this behavior in the G eq, though those are much more subtle in their effect than the Pultec,

you forgot "speculative" and "perfunctory."

those might be the most common. I try NOT to use those!

On a proper monitoring system with a beefy sub, this technique could accomplish the same thing!

Thanks for all the comments.    My main problem was that I wasn't catching on to the boost being a shelf and the cut being a peak.

Individually (i.e. without using the boost), I'm not sure the cut is a bell curve.

But when the boost and cut are combined, a bell-curve shaped "dip" happens. It generally seems to occur at a somewhat higher frequency than selected, if that makes sense.

It isn't.

However, when boosting and cutting at the same time the band interaction makes it *act as* a bell filter...  which is what you need to know for the purposes of this explanation.
