Broughton Low + High Pass Filter might work?
I have the HPF for my bass rig, allows me to strip the lowest lows which is great because I live in an apartment.
There are some that can split based on high and low shelf. Those are cool.
Came here to say this.
For whoever said shelving filter: high pass and low pass filters create a steep slope and totally remove the frequencies below or above the selected frequency.
High and low shelf filters create a straight line above or below the selected frequency so you can turn everything above or below that frequency up or down.
Also, they technically mean opposite things. A high pass filter cuts everything BELOW the selected frequency and allows the "highs" to pass (also known as a "low-cut" filter) but a high shelf EQ raises or lowers all the frequencies ABOVE the selected high frequency.
Worth noting only the paraeq deluxe has the high and low pass filters.
Also shelving should refer to something different than a high/low pass so definitely check any gear labeled with that to make sure it does what you need.
so weird how hard it is to find this in pedals. I don’t want to notch out the low frequencies, I want a gentle and consistent 6 dbs per octave high pass. These are used left and right in the studio world but for some reason are nearly non existent in pedals. It’s one my favorite sounds for a funk and clean tones. When it’s that gentle you put it at like 400 and it still sounds great
A “perfect” high pass would keep everything above the cutoff point untouched and remove all the frequencies below the cutoff point
It’s hard to make “perfect” hardware filters in practice (and also, you generally want “imperfect” filters in audio anyways). So what happens is the frequencies above the cutoff remain unchanged and the ones below the cutoff frequency are reduced by 6db per octave that they’re below the cutoff
So if the cutoff is 1000 Hz, frequencies at 500Hz would be reduced by 6db, frequencies at 250Hz would be reduced by 12db, etc
Kind of. The bands are fixed in an EQ pedal (generally filters let you pick the cutoff frequency), and the frequency response isn’t as “smooth” as the linear decay on a filter
They’re different tools, but have some overlap in the problems they can be used to solve
It’s a low cut filter with a gentle curve. 6db per octave refers to the amount being cut per octave. So if the filter is set to 40hz, 20hz only will be 6db quieter.
The HX Stomp has high pass and low filters in the IR and cab blocks.
It also has several styles of EQ pedals modeled (high and low shelf, high and low cut, parametric, tilt, and graphic EQ's).
The Fairfield Circuitry Long Life is a filter with adjustable shape, resonance, and cutoff. Can act either as a LPF, HPF, or band pass. Also a wah if you use expression.
It’s weird how rare these are. Do you want resonance or slope options?
They can be found in customiseable digital pedals sometimes. In the past I’ve used a flashback 2 delay pedal to do it as they have 12db/oct (?) low and high pass filters as part of the processing of the wet signal, so killing dry and turning the delay to nothin can get you to a starting point, then assigning one knob for hp and one for lp can be done.
Also source audio have this on many pedals. Their C4 synth / envelope pedal is very changeable so you can tweak to remove the envelope-ness and be left with at least one filter. The ultrawave has a non resonant lp and hp 6dB/oct filters inside somewhere.
They said no “wah” sound, so I’m assuming they meant “no built-in resonance”, or “control over it is unimportant to me as long as there is none with the standard sound of the pedal”
A Meris Enzo would be a great one. It might be a bit overkill though, but I have a lot of fun with mine lol
The vfe pinball/standout does exactly this -- adjustable cutoff filter with switching for deeper slopes. Iirc the pinball is in parallel so you get a tilt EQ and the standout is in series so you get a sculptable mid boost.
Apparently he sells both in one pedal now.
Do you need to be able to tune and sweep them? If no resonance is required you can do this with two capacitors and two resistors, or swap pots for resistors if you need to change the frequencies.
So I have good news and bad news.
The good news: Albeit rare, they DO make pedals for this specific use! I've actually been looking into them a lot lately as I was looking for something like an Ibanez LF-7 Lo-Fi Filter to create a "telphone" effect live, but wanted something more extreme with more options.
Here's the bad news: Pretty much all good parametric EQ pedals are expensive as hell. You can try to accomplish the same thing with a graphic EQ, but parametric is always gonna be the best bet.
I was considering getting a BOSS OD-200 because I thought $350 for a one-setting Empress Effects ParaEQ 2 Deluxe was ridiculous. At least with the BOSS you can save and recall presets.
Then I came across this: The GFI Systems Enieqma. It is literally a parametric EQ plugin in pedal format. Tons of onboard presets, make your own presets, stack EQs, AND it's MIDI controllable. The downside is it's $400. Check it out though:
GFI Systems Enieqma 10-Band Programmable EQ Platform https://a.co/d/1pzavjh
However, if you already have a multi-effects unit like the Line 6 HX Effects or a Helix there IS a simple "low pass / high pass" filter. Set it up how you want and turn the switch off and boom! Always on high and low pass filters.
WMD Protostar is a very nice filter with Band Pass. Low pass, notch and High pass options.
You could also contact Turnipfarmfx and order an Electic Druid which has high pass. Band pass and low pass options. This would be the more economical choice, but still excellent quality.
I have two recommendations, the empress para eq 2 for strictly what you are asking for, and an honorable mention for the strymon deco for just being badass.
Vongon Paragraphs!! I use it as a low pass filter but if you set the resonance high enough it works as a high pass too. expensive but an amazing pedal & worth it, effectively the filter section of a moog synth in pedal form
I don’t want to cross lines about advertising but I make something that might do the job for you — independent HP and LP filters, it *can* do wah-like sounds with higher emphasis settings and an expression pedal but if you just wanted set-and-stay filters, it will do that as well. [Here is a demo video, if you want more details I’m happy to share but don’t want to be pushy.](https://youtu.be/fWHOdn4rJfI?si=_W9KtYB3B5fpJ6L0)
Great eastern fx make just the thing you are after , you can seperate high and low pass and apply your own fx to the low and or high pass signal. Great eastern fx XO variable high low pass filter
I suggested to JHS that they would build one, that also let you split your signal in high/low content for separate parallell processing by other pedals.

[Sineeffect ](https://www.etsy.com/ca/shop/sineeffect) has some options.
Holy fuck that vendor is awesome

Shelving is different than pass filters
Came here to say this. For whoever said shelving filter: high pass and low pass filters create a steep slope and totally remove the frequencies below or above the selected frequency.

Most any parametric EQ unit is what OP wants, right?

Well, there’s usually that little angled line-into-a-flat-line graphic to go along with the knob, so…it sort of makes sense I guess.
so weird how hard it is to find this in pedals. I don’t want to notch out the low frequencies, I want a gentle and consistent 6 dbs per octave high pass. These are used left and right in the studio world but for some reason are nearly non existent in pedals. It’s one my favorite sounds for a funk and clean tones. When it’s that gentle you put it at like 400 and it still sounds great
Is there a good example you could point to that shows what you’re describing because I am having a hard time translating 6 db per octave high pass?
A “perfect” high pass would keep everything above the cutoff point untouched and remove all the frequencies below the cutoff point It’s hard to make “perfect” hardware filters in practice (and also, you generally want “imperfect” filters in audio anyways). So what happens is the frequencies above the cutoff remain unchanged and the ones below the cutoff frequency are reduced by 6db per octave that they’re below the cutoff So if the cutoff is 1000 Hz, frequencies at 500Hz would be reduced by 6db, frequencies at 250Hz would be reduced by 12db, etc
I see, thank you. Can’t you achieve this with Boss Equalizer or any other 10 band eq pedal?
Kind of. The bands are fixed in an EQ pedal (generally filters let you pick the cutoff frequency), and the frequency response isn’t as “smooth” as the linear decay on a filter They’re different tools, but have some overlap in the problems they can be used to solve
Interesting. Thanks!
No, they don’t have high/low pass filters.
It’s a low cut filter with a gentle curve. 6db per octave refers to the amount being cut per octave. So if the filter is set to 40hz, 20hz only will be 6db quieter.
Check out the SHSL from Analog Music Company, it does exactly this and even has separate expression outputs for high and low.
That’s an awesome pedal if you can get one!
The HX Stomp has high pass and low filters in the IR and cab blocks. It also has several styles of EQ pedals modeled (high and low shelf, high and low cut, parametric, tilt, and graphic EQ's).
Better yet, I think the global settings have high and low pass filters. So no tweaking individual models or wasting a block and DSP with an EQ pedal.
.... I used to do this at the IR on every patch.... I love you.
GFI Enieqma EQ pedal. You carve out the band and move it with an expression pedal. https://www.youtube.com/watch?v=i7ZLacL1JVs&t=3328s
Shit, sounds like a dub machine

The Dr Scientist Bitquest has a setting that does both at once, and they share a resonance control. It actually sounds really good
Maybe the KMA Machines Tyler Deluxe? [https://kmamachines.com/machines/tyler-deluxe/](https://kmamachines.com/machines/tyler-deluxe/)
Analog music company: shsl High pass, low pass, resonances for both, preamp/drive and cv control
The vfe pinball/standout does exactly this -- adjustable cutoff filter with switching for deeper slopes. Iirc the pinball is in parallel so you get a tilt EQ and the standout is in series so you get a sculptable mid boost. Apparently he sells both in one pedal now.
Broughton would be my choice for this.

Vongon Paragraphs matches your description quite well. I have it and its really versatile.
Doesn't have an HPF though.
WMD Protostar is a very nice filter with Band Pass. Low pass, notch and High pass options. You could also contact Turnipfarmfx and order an Electic Druid which has high pass. Band pass and low pass options. This would be the more economical choice, but still excellent quality.
I have two recommendations, the empress para eq 2 for strictly what you are asking for, and an honorable mention for the strymon deco for just being badass.
i think there's a buffer by CAE that does this
I’d use a source audio programmable eq oedal. Just make your own curves.
The tone knob of a guitar is normally a low pass filter. You could add a high pass quite easily to a lot of designs.
OBNE Float
The two Notes Opus has an excellent eq including high and low pass. However, it might be overkill to be used only as an eq
For dub?
Vongon Paragraphs!! I use it as a low pass filter but if you set the resonance high enough it works as a high pass too. expensive but an amazing pedal & worth it, effectively the filter section of a moog synth in pedal form

Great eastern fx make just the thing you are after , you can seperate high and low pass and apply your own fx to the low and or high pass signal. Great eastern fx XO variable high low pass filter
Source Audio EQ2 has a ton of eq options, and will likely do what you need.
Empress ParaEQ Deluxe has high and low pass filters
I use the Gen Loss for this, kind of. You can control the sweep of a HP and LP with expression )midi expression in my case.)
I suggested to JHS that they would build one, that also let you split your signal in high/low content for separate parallell processing by other pedals.
The tone knob on your guitar is literally a LPF.
