Best EQ Pedals HERO

Most pedals you buy come with some sort of EQ management – anything from a simple tone knob to a set of bass, mid and treble controls. Even the most ‘transparent’ effect will have an impact on the frequencies present in your sound.

But the rabbit hole of EQ control goes far deeper than that – from broad-strokes six-band EQs to programmable parametric behemoths, these units can act as helpful ‘always-on’ units, cut your solos through a band mix or work as their own distinct effect.

Parametric vs graphic EQ

EQ pedals can be broken down into two broad categories: graphic and parametric. The first is, unsurprisingly, the easier to visualise of the two – your signal’s frequency spectrum (or part of it) is broken up into a certain number of bands, each of which can then be boosted or cut with the corresponding slider. Simple enough. Non-parametric equalisers that utilise knobs instead of sliders operate in the same way, however these are less common as it’s easier to pack more bands side by side on a stompbox.

Parametric EQs similarly break things up into bands, but the precise location of where the bands fall across the spectrum can then be controlled, as can the width and shape of each band – referred to as ‘Q’. This offers an advantage over graphic EQs, which most of the time have a fixed frequency and Q for each slider.

Using an EQ

An EQ pedal can find its place in your rig in many different ways. Got a fuzz pedal that sounds great, but can’t cut through a mix? Use an EQ to reintroduce some midrange into the situation. Bass frequencies from your amp interfering with your bandmates’ sound? Use one to cut down on rumble.

They don’t have to be used as pure problem-solvers, either – the satisfying stoner-rock crunch of Queens Of The Stone Age’s Songs For The Deaf was achieved in part by slamming the maxed-out midrange of an EQ pedal into the front of an amp. Similarly, cutting everything except one band can lead to an interesting nasal, filtered sound. There are countless situations where an EQ pedal can bring your tone to life, and the best way to find out how one can work for you is to grab one and get experimenting.

What to look for when buying an EQ pedal

By-and-large, EQ pedals offer very similar things, and so breaking down their pros and cons can seem a bit tricky at first. The main battles are fought on the grounds of quality-of-life features: separate boost switching, programmability, illuminated sliders, and so on. Form-factor is another thing to consider, especially in the case of graphic EQs. If you’re strapped for space on your board, then you might have to trade that off with the number of bands your EQ pedal has.

Another thing to consider is the frequency range of the pedal – the human range of hearing (roughly) spans 20Hz to 20kHz, but the main work being done by a guitar signal seldom fills out every part of that. 100Hz is generally the bassiest frequency you’ll have to worry about, although there are exceptions. Similarly, control of frequencies above 16kHz is less common in the world of guitar EQ.

MXR Ten Band EQ

The MXR Ten Band EQ

+ Two outputs
+ Shelving on highest band
– No separate footswitch for boost

With separate level and gain controls, and of course a wide range of 10 frequencies to manipulate, the MXR 10-Band EQ offers everything you could want out of an EQ pedal. The pedal’s boost/cut range extends out by 12dB, more than enough to have a noticeable impact on your sound. There’s also separate volume and gain controls, perfect if you want to switch the pedal on for a soaring lead boost. Dual outputs and illuminated sliders are a nice touch too.

Price: ‎£134 / $129.99 Description: 10 band EQ pedal with stereo outputs and illuminated sliders Controls: Slider for each frequency band, sliders for overall volume and gain  I/O: ¼-inch in, stereo ¼-inch outs Bypass: True bypass Power: 18V DC

Empress ParaEq

The Empress ParaQ

+ Fully parametric
+ Separate boost section
– Overly complex for some rigs

Empress’ ParaEQ is perhaps the most extensive parametric EQ you’ll find in a pedal format. It offers three bands: low, between 35 and 500Hz, mid, between 250 and 5kHz, and high, between 1K and 20kHz. Each has an independent Q control, with three shapes to choose from, as well as +/-15dB of manipulation. You could use the broadest Q settings to get the pedal to act as a boost, but since Empress was kind enough to already include a separately-switchable 30dB clean boost, the EQ section is free to act on exactly the frequencies you need it to.

Price: £259 / $249 Description: Parametric EQ with three variable bands and separate clean boost Controls: Gain and frequency knobs and Q selector switch for each of the three bands, gain control for boost, independent footswitch for boost circuit, 0/-6/-12dB input pad toggle I/O: ¼-inch in/out Bypass: True Bypass Power: 9-18V DC

Boss GE-7

the Boss GE-7

+ Tried-and-tested Boss form-factor
+ Guitar-focused frequency range
– Slightly hissy at higher gain levels

It’s been around since the 1980s, and not without reason. It’s seven bands focus on the low-midrange, offering control between 100Hz and 6.4kHz. While the high-end control isn’t as precise as pedals that go all the way up to 20kHz, the range on offer is voiced more towards the core components of a guitar’s outputs, rather than across the entire spectrum of human hearing. Each band has a sizable 15dB of boost or cut, and an independent level control makes use as a solo boost that much easier, too.

Price: £85 / $119.99 Description: Graphic EQ with 7 bands and volume control Controls: Slider for each band, separate slider for overall level  I/O: ¼-inch in/out Bypass: Buffered bypass Power: 9V DC

Source Audio EQ2

+ Programmable, with presets
+ Other useful features thrown in
– Overkill for some simpler rigs

The Source Audio EQ2 offers a number of high-tech features, combining aspects of parametric and graphic EQs. While control is split into 10 bands, each can be widened or narrowed for either broad strokes or accurate fixes. There’s also shelving options for even further shaping, and every band has 18dB of boost or cut.

The EQ2 isn’t just a set of illuminated virtual sliders, either. It’s programmable, with eight accessible with just the unit, and a further 128 can be accessed with an external midi controller.

Far from just offering EQ control, the EQ2 also offers a noise gate, a dynamic limiter, a tuner and some stereo signal routing options that include: mono to stereo, stereo to stereo; and the ability to split signals and run each one through a separate EQ preset.

Price: £288 / $269 Description: Programmable EQ pedal with recallable presets, noise gate, tuner and extensive stereo routing Controls: Parameter encoder knob, preset selector knob I/O: ¼-inch stereo in/out, USB in, MIDI In/Through Bypass: Either buffered or true bypass Power: 9V DC

Wampler EQuator

+ Fine control over mids
+ Huge amount of boost on tap
– Only two Q settings

The Wampler EQuator is semi-parametric, with two controls for everyone’s favourite bandwidth area: the midrange. Bass and treble’s frequency locations are fixed to keep things simple.

In terms of the two midrange controls, Mids 1 has a narrow Q, while Mids 2 has a wider Q – so both notch adjustments and broad midrange boosts are catered for. Mids 1 can vary between 238Hz to 5kHz, boosting or cutting by 15dB while Mids 2 can range from 480Hz to 4.8kHz and boost or cut by a whopping 25dB.

Price: ‎£196 / $199 Description: Semi-parametric EQ with two adjustable midrange bands Controls: Bass/Mids 1/Mids 2/Treble level, Master volume, Mids 1 frequency, Mids 2 Frequency  I/O: ¼-inch in/out Bypass: True Bypass Power: 9V DC

Old Blood Noise Endeavors EQ + Buffer

The OBNE EQ Buffer
Image: OBNE

+ Bundles in two ‘utility’ functions
+ Sleek, compact design
– Only 3-bands

A buffer can be an essential part of your board, mitigating the treble loss that comes with long cable length and/or large numbers of true-bypass pedals before your amp. Old Blood Noise Endeavours combine an always-on high-quality buffer with a switchable three-band EQ, meaning two utility pedals combined into one.

While only three sliders won’t offer extreme control over narrow frequency bands, the pedal can still let you rejuvenate your signal after overdrive or fuzz, or give it more character before it runs into a flatter preamp section.

Price: £99 / $99 Description: Always-on buffer with switchable 3-band EQ Controls: Slider for each frequency band, footswitch to engage EQ I/O: ¼-inch in/out Bypass: Buffered bypass Power: 9V DC

Mooer Graphic G

+ Small footprint
+ Affordable
– Limited features

The Graphic G is no departure from Mooer’s focus on budget, compact pedals. Its small footprint means there’s only five bands here, ranging from 100Hz to 4kHz. There is an overall level control, too, but that’s just about it – no extra features here. But given the size of the pedal and its impact on your wallet, it might be a handy addition to your ‘board.

Price: £56 / $68 Description: Small five-band graphic EQ with level control Controls: Slider for each frequency band, illuminated knob for level control I/O: ¼-inch in/out Bypass: True bypass Power: 9V DC

Maxon GE601

Maxon GE601

+ Can use as a buffer
+ Fine control over its frequency range
– That range is smaller than some EQs

The six bands that the GE601 offers cover a slightly smaller range than some pedals, going from 100Hz to 3.2kHz – which isn’t inherently bad, as it means a more precise set of slices out of the frequency spectrum. The GE601 also features buffered, JFET bypass switching with a low impedance output, meaning it plays well with long cable lengths or other effect units without loss of treble clarity. There is only 12dB of boost/cut on tap for each frequency band, meaning that it’s less suited to extreme adjustments.

Price: £115 / $159 Description: Six-band graphic EQ Controls: Slider for each frequency band, plus a slider for overall level I/O: ¼-inch in/out jacks Bypass: buffered bypass Power: 9V DC (Battery) / 10V DC (AC-adaptor)

KMA Machines Tyler Frequency Splitter

+ Innovative design
+ More ‘inspiring’ than pure utility EQs
– Doesn’t offer full-spectrum frequency control

This is an entirely different approach to an EQ pedal than the others on this list, but some of the same principles are at work. Your signal is split into two paths – one of which goes through a high-pass filter, and the other through a low-pass filter, each with a variable cutoff. Both filters can then be run through separate effects loops, and then recombined to your liking, depending on the setting of the mix knob. This has endless potential applications, such as creating a thunderous low-end run through four Sovtek Big Muffs, while your high-end chord definition is provided by a low-gain Klon. There are probably more sensible uses, because as anyone who’s used high- and low-pass filters knows, they can be incredibly powerful for shaping a sound.

Price: £209 / $259 Description: High- and low-pass signal splitter with independent effects loops for both filters. Controls: Low-pass filter frequency, level, phase inversion switch, mix, high-pass filter frequency, bypass/LP/HP footswitches I/O: ¼-inch in/out, HP send/return, LP send/return Bypass: True bypass Power: 9V DC

Free The Tone PA-1QG

The Free the Tone PA-1QG
Image: Free The Tone

+ Programmable, with presets
+ Separate footswitch for preset selection
– Expensive

When a single EQ pedal costs more than some guitars – it’s likely going to have some tricks up its sleeve. The bands on offer here range from 50Hz to 10kHz, with an illuminated display to let you know what’s going on. Four presets can be recalled using the on-board footswitch (and this includes the level control, perfect for switching into a solo from an ‘always-on’ eq sound), while 99 are accessible with MIDI. And don’t let the digital look fool you – the signal path here is 100 percent analogue, with digital circuitry only being used to control the parameters.

Price: £365 / $380 Description: Programmable, MIDI-controlled EQ pedal with 10 bands and switchable presets Controls: Left/right cursor keys, parameter encoder wheel, instrument/line level selector switch I/O: ¼-inch in/out, MIDI in/out/through Bypass: ‘Holistic Tonal Solution’ bypassing Power: 9V DC
