Explain like I'm 5, what is going on in this pedal to make is sound like this, please?

at about 6:10 in this video, this demo switches to show off the low pass filter of this pedal. If I were to ask you how to make a pedal that sounds just like this, or show me a pedal that I can make that does this, what would you show me? What is happening to make that low end distortion/fuzz sound? (obviously a low pass fiIter...but...) I have analysis paralysis right now, trying to choose a permanent fuzz for my board. Should I just build a muffin factory to help me narrow my view? I know that I really like the low end sound, but there are 8.2 billion fuzz pedals out there, and a lot of them sound the same, or very similar. When I think if fuzz, this is the sound I want to make. At least, right now it is.

I think the Moonbow is an Oberheim SEM style filter with a console type drive in front of it. The Hudson Broadcast (PPCB Simulcast) and JHS Crayon (PPCB Pastel Preamp) are both based on consoles and are in the same ballpark sound-wise to me. Rob also posted a picture of the Catalinbread Airstrip on his bench which is also based on a console but is a bit heavier gain than the aforementioned.
 
Does the Acrobat get you in the same ball park? I haven’t built up mine yet so can’t comment.
 
However, I'm sure someone around here could help you alter the tone stack of the right pedal to get you close.

I'm obviously not that guy.

You would just turn down the tone knob on your guitar. When that Res knob is turned down, the cutoff knob is the same thing.
 
With tongue in cheek I take up your "explain like I'm 5" prompt.

Use any distortion pedal
Turn all of its knobs UP
into Any EQ pedal
turn most of its knobs DOWN.

Done.
I mean…i meant it. Ive been playing for just over a year. Ive played every day since, and now have a 16 pedal board. Im trying to learn ad much as I can about all of it. If its that simple then great! Ill add an eq pedal to the list!

I've been playing for 16 years but sound like I've been playing for just over a year so.... yeah...
Like usual I'm right in my own way, but I'm also just messing with you.
There is more than one way to get there.

I've been playing for 58 years, but the arthritis is getting worse and worse. You'll soon be better than I am! I recently strained my left ring finger in a five fret stretch. Normally I wouldn't have, but I was quickly switching back and forth from chords to lead and *missed* {{{{{O*U*C*H}}}}}

SOB couldn't play for a month....

Gonna have to start playing slide...
 
So is this it? Can you add this to a pedal circuit?
From the look of it it’s a high pass/low pass after fuzz - so the time sig bit you pointed too it’s a fuzz into a low pass - so chopping off the highs from the drive - I do that a lot as a bass player if not using a can sim as full range horns in my bass cab have more top end than guitar cabs …
The resonance adds a peak before the cutoff.
The frequency interchange woild do high pass, and low pass - but not the resonance.
The ppcb pro-filter which is the craig Anderson circuit woild have the resonance - build it stand alone and you can stick all your drives into it and shape them!
 
The PPCB Minnow might also be worth a look. It’s based on a Tom Oberheim designed filter, and it’s got some cool modulation options as well.

The Korg MS-20 filter is another synth classic that seems to pop up in DIY somewhat frequently. Not sure if anyone currently sells a guitar friendly PCB.

I picked up this kit: https://www.cctv.fm/product-page/ms...D6U0QC_pf7i_zOw_hVg03KAIeLW0CxQGHFtYdcrlan7bo
that I’m planning to turn into a pedal. Maybe try to kludge a little envelope follower and/or LFO circuit in there while I’m at it.

This right here is the stuff I came here looking for! Thanks for sharing your experience!
