This is right from Gustav's site PCB Grinder

"The heritage of this EQ goes back to the Calrec console EQ designs, which were refined and developed by the late Barry Porter.

The files and schematics for Porter's "NetEQ" were available to the public, and after Barry's passing, it grew to be a popular build in DIY circles, with many additions and modifications.

Based on circuit boards offered by PCB Grinder, various renditions were built for (and by) mastering engineers, and it soon became a favoured tool, in its own right, and on par with the coveted Sontec and GML EQs.



The "Grinder" part?

In 2016, I had already built a few custom Porter EQs, and I started rethinking parts of the original circuit, based on the experience gathered.

To be completely honest, the original idea was to put out a scaled back, "less controls", but "easy-to-DIY" version as a kit, but rather than cutting corners, I got lost in the details at every step of the process.

So instead, it turned into a two year development and listening project, with numerous hours spent on circuit design and countless hours spent in front of speakers, with friends and colleagues.

What I have now feels like a very personal iteration of the circuit, with a new level of refinement. Still a Porter, but also, very much, a Grinder.



So what's new?

In essense, all thats been left untouched from the original Porter layout, is the parallel filtering section.

The In- and output sections have been completely reengineered, a Mid/Side matrix has been added, and the Q was changed to display even gain behaviour.

We also did extensive, blind listening tests, and even developed an opamp switching circuit to do so, before we settled on our choice of opamps. Not the most esoteric available, but in our opinion, the best for this circuit."

Looks really cool. Kind of like what HCL did with the Thermos, reimagining the input and output stages. Also the IO chips (and filter chips) make SO much difference its really hard to believe, and I do think one could spend a year testing different ones to find the right combo.

Yeah Man.....

I am hoping this gives me a stealthy M/S capable main parametric
that fits nicely in the workflow. The Soma was ultimately was a bit soft
with the other pieces in my desk...

I'll keep you posted!

I have been through the buzz, the soma and most other modern EQs
and I was curious about Gustav's take on the Porter.
I am always changing gear.....

@ nomatic lets us know how it sounds. Earlier this year I got some sound clips of the unit with specific settings on a mix and it sounded really dark to me. I said to myself this couldn't be while listening to the files.

I can't picture this particular topology sounding dark based on the design lineage
but we will see....

Well I got the unit today and went ahead and did a record and must say I
am quite pleased. Overall the character is elegant and tightly integrated with the music with no transient smear...

I will report back after a few records....

I am so happy the unit found you well!

Price will be adjusted slightly upwards in a month, because he final tweaks (like getting the perfect knobs) added some cost - if it beats out the incredible contenders you've had in play, I should probably just double it.

Im booked through August, but I have a PG build coming in September. Adding another unit or two while Im at it would be so much more efficient on my end.

[email protected] if anyone has any questions, or would like to add a unit to the build queue at my shop!.

Hey Gustav,
Its a truly great Mastering eq and hangs with the best...
As with all things it is how the combination of analogue gear works in
a specific chain but I am quite happy with this combo....
The thing I like is how integrated the EQ is with the music.
Transparent but much better than a plug-in and the MS implementation is great.

Really nice work!

@ nomatic would you be so kind to print a sample, ala mcsnare settings, with the mix in the EQ Shootout thread?

McSnare settings?!

I don't think I know what those are?

Anyway I am going to meet McSnare so he can hear the EQ at his place tomorrow so I will ask.....

Yeah, very important detail

It was interesting to hear the Grinder next to a modified "golden Sontec
and a Millenia with the Forrsel mod.....
It hung with both of those units.
The Sontec Mcsnare has is kick ass for sure but I am quite happy with the PG
in comparison...
It would be best to have both!

I'm interested to hear your description on the sonic differences between the PG and Mcsnare's Sontec.

To Compare and contrast.......
The sontec sounds classic and clear with a recognizable excitement in the opamps and the shape of the Curves. (you can't argue it kills)
The PG has a more stealth footprint as far as the circuit but in general sounds
tightly integrated with the program and seems almost immune to harming
the music even in extream boosts. I think the Sontec's Q goes a touch wider.
The fossell has a very nice high shelf and has a particular shimmer
that is compelling but it is quite active sounding to my ears.
The magic of the PG Gustav built is how passive it sounds..
So smooth without interfering with the transients with enough character
to make things sound better for it.
For those of us that don't have a Muth modified classic Sontec it is a great
choice for a main parametric.
I would recommend having both!

Hey Michael when you have some time please give a pass with your PG EQ and update the monster thread of mastering eqs:

I'm shooting out Mastering EQs...

If you can't find the original mix just ring the bell, I still have all the files from everyone...

these are the mcsnare settings:
+1 50hz shelf (56Hz on 315)
+1 100 hz med Q
+1 8200 hz med Q (+2 at 8100 on 430B)
+1 10K shelf

I know I've been saying this a lot lately but that is exactly how I feel about it.

Nicely put.

Well, I surrender.

The other units are fantastic. The cost of those switches alone must be huge. For 2800 schmekels, seems like a steal. I'm in.

Do you know if the Sontec is using the HS-2000s or another DOA?
