EQ Cheat Sheet: Frequency Reference for Every Instrument
Cut, boost, and filter targets for drums, bass, vocals, guitars, keys, and more — the reference guide every producer should have on hand during a mix session.
The seven key frequency bands and what each contributes to your mix. The 250–500 Hz "mud zone" is the most common culprit in unclear, amateur-sounding mixes.
How to Use This Cheat Sheet
The frequencies listed here are starting points, not laws. Every recording is different — a kick drum recorded in a bright room with a Shure Beta 52A sounds different from one sampled from a 1970s soul record. Use these ranges to know where to look, then trust your ears to make the final call.
The single most important EQ principle: subtractive before additive. Identify what's wrong with a sound and cut it first. Only boost if there's something genuinely missing after you've removed the problem. Most amateur mixes have too many boosts and not enough cuts — the result is a dense, congested, loud mix with no space or clarity.
Frequency Map Overview
| Range | Frequency | Character | Common Action |
|---|---|---|---|
| Sub-Bass | 20–60 Hz | Felt more than heard. Weight, rumble, power. | HPF non-bass tracks here. Keep for kick and 808. |
| Bass | 60–250 Hz | Warmth, punch, body, fullness. | Boost kick around 80 Hz. Cut bass mud 150–200 Hz. |
| Low-Mid (Mud) | 250–500 Hz | Boxiness, mud, muddiness, warmth. | Cut most tracks here. Biggest clarity win in a mix. |
| Midrange | 500 Hz–2 kHz | Honk, nasal, phone-like, body. | Cut nasality at 800 Hz–1 kHz. Guitar body lives here. |
| Presence | 2–5 kHz | Forward, aggressive, cutting, intelligibility. | Boost vocals 2–4 kHz for presence. Cut for harshness. |
| High-Mid | 5–10 kHz | Sibilance, brightness, bite, detail. | De-ess vocals 5–8 kHz. Cymbal attack lives here. |
| Air | 10–20 kHz | Sparkle, openness, air, shimmer. | High-shelf boost on vocals and room mics for air. |
Kick Drum EQ
| Frequency | Action | Result |
|---|---|---|
| Below 20–30 Hz | High-pass filter | Removes inaudible sub-rumble that wastes headroom |
| 60–80 Hz | Boost (gentle, wide) | Sub weight and power |
| 80–100 Hz | Boost (narrow, +2–4 dB) | Punch and fundamental impact |
| 300–400 Hz | Cut (narrow, −3–6 dB) | Removes cardboard boxiness |
| 3–5 kHz | Boost (subtle, +2–3 dB) | Click and attack — helps kick cut through |
| 6–10 kHz | Cut or leave | Reduce if kick sounds too clicky or harsh |
Key tip: The relationship between the kick's fundamental frequency and the 808/bass is critical. If your kick's fundamental is at 80 Hz, consider scooping the bass slightly at 80 Hz and letting the kick own that space. Sidechain compression (bass ducking on kick hit) also solves this without EQ.
Snare & Clap EQ
| Frequency | Action | Result |
|---|---|---|
| Below 80–100 Hz | High-pass filter | Removes low-end mud that competes with kick |
| 150–250 Hz | Cut (narrow, −3–5 dB) | Removes boominess and mud |
| 200–250 Hz | Boost (subtle) or cut | Body and fatness — boost for vintage, cut for modern tight snare |
| 900 Hz–1 kHz | Cut (narrow) | Removes nasal, boxy character |
| 2–4 kHz | Boost (+2–4 dB) | Snap, crack, presence — the snare "cuts through" |
| 6–10 kHz | Boost (gentle, wide) | Air and sizzle — adds brightness to snare top |
Key tip: A layered snare (one sample for body, one for crack) often sounds best with EQ applied separately to each layer — boost the body sample at 200 Hz, boost the crack sample at 3 kHz, then blend.
Hi-Hats & Cymbals EQ
| Frequency | Action | Result |
|---|---|---|
| Below 300–500 Hz | High-pass filter (steep) | Removes all low and low-mid content — hi-hats don't need it |
| 2–4 kHz | Cut if harsh | Reduces metallic harshness and ear fatigue |
| 6–10 kHz | Boost or cut to taste | Bite and attack of the hi-hat |
| 10–16 kHz | Boost (gentle) | Air and shimmer — opens up the top end |
| Above 18 kHz | Low-pass filter | Reduces digital harshness and aliasing noise |
Key tip: Hi-hats and cymbals occupy the same frequency space. If you have multiple cymbal tracks, use EQ and panning to differentiate them — one slightly brighter and panned left, one slightly darker and panned right.
Bass Guitar & 808 EQ
| Frequency | Action | Result |
|---|---|---|
| Below 30–40 Hz | High-pass filter | Removes inaudible sub content that consumes headroom |
| 60–80 Hz | Boost (gentle, wide) | Sub fundamental weight |
| 80–120 Hz | Boost (focused) | Punch and definition of bass fundamental |
| 150–300 Hz | Cut (narrow, −2–4 dB) | Removes mud and boominess that clashes with kick |
| 700 Hz–1 kHz | Boost (+1–3 dB) | Note definition and presence on smaller speakers |
| 2–4 kHz | Boost (subtle) | Adds harmonic bite and helps bass translate on earbuds |
808-specific tip: The 808's pitch determines where its fundamental sits in the frequency spectrum. A pitched 808 on C2 has its fundamental around 65 Hz; on A2 around 110 Hz. EQ must follow the pitch — your boost target changes with every note. For this reason, dynamic EQ is particularly useful on tuned 808 basslines.
Vocals EQ
Vocals are usually the most important element in a mix — they receive more careful EQ attention than any other instrument.
| Frequency | Action | Result |
|---|---|---|
| Below 80–120 Hz | High-pass filter | Removes handling noise, room rumble, chest proximity effect |
| 150–250 Hz | Cut (narrow, −2–4 dB) | Removes muddiness and boxiness in the low-mid |
| 300–500 Hz | Cut if boxy | Reduces cardboard, telephone-like quality |
| 800 Hz–1 kHz | Cut (narrow) | Removes nasal, honky quality |
| 2–4 kHz | Boost (+1–3 dB) | Presence and intelligibility — vocal cuts through the mix |
| 5–8 kHz | De-ess / cut if harsh | Reduces sibilance (harsh S, T, SH sounds) |
| 10–16 kHz | High-shelf boost (gentle) | Air and openness — makes vocal sound professional and airy |
Key tip: The exact frequencies vary by vocalist. Sweep a narrow boost slowly through problem areas while the vocal plays to identify exactly where harshness, mud, or nasality lives — then cut. Every voice is different; these are search zones, not guaranteed targets.
Electric Guitar EQ
| Frequency | Action | Result |
|---|---|---|
| Below 80–100 Hz | High-pass filter | Removes low-end competition with kick and bass |
| 200–400 Hz | Cut (−2–4 dB) | Reduces mud and boxiness — the most common electric guitar fix |
| 800 Hz–1 kHz | Cut if harsh | Removes midrange honk and boxy character |
| 2–4 kHz | Boost or cut | Presence — boost to cut through, cut to push back in the mix |
| 5–8 kHz | Boost subtle | String detail and pick attack |
| Above 10–12 kHz | Low-pass filter (optional) | Removes amp hiss and digital harshness |
Key tip: In a dense mix with multiple guitars, use complementary EQ — cut one guitar in the 2–4 kHz range and boost the other, then pan them opposite. This creates width and frequency separation simultaneously.
Acoustic Guitar EQ
| Frequency | Action | Result |
|---|---|---|
| Below 80–100 Hz | High-pass filter | Removes boom and low-end rumble |
| 100–200 Hz | Cut if boomy | Reduces excessive body resonance |
| 300–500 Hz | Cut (narrow, −2–4 dB) | Removes muddiness — very common on acoustic guitar |
| 2–5 kHz | Boost (gentle) | String definition and pick attack |
| 10–12 kHz | High-shelf boost (subtle) | Air and sparkle — makes acoustic guitar sound open and live |
Keys & Synths EQ
Keys and synths span the full frequency range — from deep sub pads to bright bell-tone leads. EQ approach depends heavily on the role the sound plays in the mix.
| Sound Type | Key EQ Actions |
|---|---|
| Pads / Atmosphere | HPF at 80–150 Hz. Cut presence (2–5 kHz) to push back. LPF at 8–12 kHz to keep warm and distant. |
| Lead Synth | HPF at 100–200 Hz. Boost 2–4 kHz for presence. High-shelf boost for brightness if needed. |
| Piano | HPF at 40–60 Hz (keep warmth). Cut 200–400 Hz to reduce muddiness. Boost 3–5 kHz for note clarity. |
| Rhodes / Electric Piano | HPF at 80 Hz. Cut around 300 Hz if boxy. Boost 2–3 kHz for that classic Rhodes chime. |
| Bass Synth | HPF at 30 Hz. Boost fundamental at 60–100 Hz. Add presence at 800 Hz for translation on small speakers. |
| Bell / Pluck | HPF at 200–400 Hz. Focus energy at 2–6 kHz for attack. Cut harsh frequencies 3–4 kHz if they clash with vocals. |
Mix Bus EQ
Mix bus EQ is applied to the stereo output of the entire mix. Use it sparingly — a few dB at most. If you need large corrections on the mix bus, fix the individual tracks instead.
| Frequency | Action | Result |
|---|---|---|
| Below 20–30 Hz | High-pass filter | Removes inaudible sub-rumble from the entire mix |
| 100–200 Hz | Cut (very gentle, −1–2 dB) | Tightens low end if mix sounds boomy |
| 300–500 Hz | Cut (very gentle, −0.5–1.5 dB) | Adds overall clarity to the mix — reduces mud globally |
| 2–4 kHz | Boost or cut (−1 to +1 dB) | Forward or backward overall presence |
| 10–16 kHz | High-shelf boost (gentle, +1–2 dB) | Opens up the mix, adds air to the whole track |
Key tip: The most useful mix bus EQ move is often the gentlest — a 1–2 dB high-shelf boost above 12 kHz (the "Pultec trick") that adds a sense of openness and professionalism to the entire mix without touching individual tracks.
Golden EQ Rules
- Cut first, boost second. Identify and remove problem frequencies before adding anything.
- High-pass everything. Apply a high-pass filter to every track that doesn't need sub-bass — hi-hats, guitars, synths, vocals, room mics. This is the single most impactful mix clarity move available.
- Use narrow Q for cuts, wide Q for boosts. Narrow cuts are surgical — they remove a specific problem. Wide boosts are more natural-sounding — they add character without a resonant peak.
- The mud zone is 250–500 Hz. Almost every unclear, amateur-sounding mix has too much energy here. When in doubt, cut here first on non-bass tracks.
- Carve space, don't add more. If an element isn't cutting through, the solution is usually to remove competing frequencies from other elements — not to boost the problem element.
- EQ in context. Always make EQ decisions with the full mix playing, not in solo. An element that sounds too thin in isolation often sounds perfect in context.
- Reference against commercial tracks. A/B your mix against a reference track at the same loudness every 30 minutes. This immediately reveals tonal imbalances your ears have normalised to.
- Less is more. If you're applying 10 dB of boost anywhere, there's almost certainly a source issue that EQ can't fix. Large boosts reveal recording problems that should be addressed at the source.
EQ Exercises
🟢 Beginner — The Sweep Technique
On a vocal or guitar track, insert an EQ with a narrow bell filter (Q around 5–8) boosted to +10 dB. Slowly sweep the frequency from 100 Hz upward to 10 kHz while the track plays. Listen for the frequency that sounds most offensive, harsh, or problematic — you'll hear it clearly because the boost exaggerates it. Once found, convert the boost to a cut of −3 to −6 dB and widen the Q slightly. This is the professional "sweep and cut" technique for finding problem frequencies by ear. Repeat on every track in your mix session.
🟡 Intermediate — High-Pass Everything
Open a finished mix session. On every track except the kick drum and bass, apply a high-pass filter. Start at 80 Hz and move it higher until you can hear the low-end content disappearing from that instrument — then back it off slightly. The goal: remove as much low-end from non-bass tracks as possible without making them sound thin. Export the mix, then A/B it against your pre-HPF version at the same loudness. The difference in low-end clarity and mix separation will be immediately audible. This exercise teaches more about mix clarity than almost any other single technique.
🔴 Advanced — Frequency Carving Challenge
Take a mix with at least 16 tracks. Apply EQ to each instrument using only subtractive EQ — no boosts whatsoever. Your only tools are cuts and high-pass/low-pass filters. The constraint forces you to make every element fit by removing what conflicts, rather than boosting what's missing. When finished, compare to a mix where you used boosts freely. Most producers find the subtractive-only mix has more clarity and space. Only after completing this exercise should you add boosts back — you'll use dramatically fewer of them.
Frequently Asked Questions
What frequencies should I cut on a kick drum?
Cut the kick drum around 300–400 Hz to reduce boxiness, and apply a high-pass filter below 20–30 Hz to remove inaudible sub-rumble. Boost around 80–100 Hz for punch and 3–5 kHz for click and attack.
What frequency range does the human voice occupy?
The human voice spans approximately 80 Hz–12 kHz. The fundamental frequency of most voices sits between 100–300 Hz. Presence and intelligibility live at 1–5 kHz. Air and breathiness appear above 8–10 kHz. High-pass filters on vocals are typically set between 80–120 Hz.
What is the muddy frequency range in a mix?
The muddy frequency range is generally considered to be 200–500 Hz. This is where many instruments accumulate low-mid energy simultaneously — bass, kick, guitars, and vocals all have content here. Cutting in this range on supporting elements clears space and improves mix clarity significantly.
What is the presence range in EQ?
The presence range is approximately 2–5 kHz. Boosting in this range adds forward, in-your-face character to vocals, snares, and lead instruments. Cutting in this range pushes elements back in the mix and reduces harshness. Most mix engineers are cautious with presence boosts because overuse creates listener fatigue.
Should I cut or boost with EQ first?
Cut first, then boost only if needed. Most mix problems are caused by too much of something — mud at 300 Hz, harshness at 3 kHz, boom at 100 Hz. Identify and cut the problem frequency first. Only add boosts if there's genuinely something missing after removing the problem.
What is a high-pass filter (HPF) and when should I use it?
A high-pass filter allows frequencies above its cutoff point to pass through while attenuating everything below. In mixing, HPFs are applied to almost every track except kick drum and bass to remove sub-bass buildup that clutters the mix. Typical cutoff frequencies: vocals 80–120 Hz, guitars 80–100 Hz, hi-hats and cymbals 300–500 Hz, synth pads 60–100 Hz.
What is a low-pass filter (LPF) and when should I use it?
A low-pass filter allows frequencies below its cutoff point to pass while attenuating everything above. LPFs are used creatively to push elements back in the mix, to warm up harsh-sounding tracks, and on reverb returns to prevent wet signal from adding unwanted brightness.
What Hz should I boost for bass guitar punch?
Boost bass guitar around 80–100 Hz for fundamental weight and punch. Add presence and note definition at 700 Hz–1 kHz. Cut the muddy buildup around 250–400 Hz. Apply a high-pass filter below 30–40 Hz to remove inaudible sub-rumble.
What EQ frequencies make a mix sound professional?
A professional-sounding mix typically has a clean low end (careful high-pass filtering across all non-bass tracks), a clear midrange (strategic cuts in the 200–500 Hz mud range), forward but controlled presence (judicious 2–5 kHz management), and natural air (gentle high-shelf boosts above 10–12 kHz on vocals and drums).
Practical Exercises
Identify and Cut the Mud Zone
Open your DAW and load a full mix or a vocal track. Solo the vocal or lead instrument. Open a parametric EQ plugin and set it to a narrow Q (high specificity). Starting at 250 Hz, slowly sweep upward to 500 Hz while playing the track. Listen for boxiness, dullness, or that 'honky' quality. When you hear it, place a cut at that frequency (–3 to –6 dB). Don't boost anything—only subtract. Solo the track off and listen to the difference in clarity. Your goal: remove one mud frequency and hear the track breathe better.
High-Pass Strategy Comparison
Load three different non-bass tracks into your DAW (vocal, guitar, pad, or any melodic source). Duplicate each track twice. On the first duplicate, high-pass at 80 Hz with a gentle slope. On the second duplicate, high-pass at 250 Hz. Compare all three versions (original, 80 Hz, 250 Hz) by toggling between them. Ask yourself: Which sounds clearest without losing body? Does the 250 Hz high-pass remove too much warmth? Where's the sweet spot for this specific instrument? Document your decision and explain why. This teaches you that the cheat sheet is a starting point—your ear makes the final call based on the actual recording.
Full Mix EQ Overhaul Using Frequency Mapping
Load a complete mix (drums, bass, vocals, guitar, keys) or build one from stems. Create an EQ chain strategy for every track using the article's frequency map. Start subtractive: identify the mud zone (250–500 Hz) on all non-bass instruments and cut problem frequencies. High-pass every track that doesn't need sub-bass. Then, selectively boost presence (2–5 kHz) on vocals and snare for punch, and air (10–20 kHz) on cymbals for shimmer. Before and after: render both versions and A/B them. Your goal is a mix that sounds clearer, more spacious, and less congested—achieved through strategic cuts and minimal boosts. Document each decision and why you made it.
Frequently Asked Questions
The 250–500 Hz range accumulates boxiness and muddiness from multiple instruments, making mixes sound unclear and amateur. Cutting here first on non-bass instruments is the single biggest clarity win you can get, which is why it's the most common problem in dense, congested mixes.
Subtractive EQ removes problem frequencies (cutting), while additive EQ boosts desired ones. The cheat sheet recommends cutting first because most amateur mixes already have too many boosts, resulting in a dense, congested sound with no space. Only boost after you've identified and removed what's actually wrong.
No—use the rule of thumb: high-pass every track that doesn't need sub-bass (20–60 Hz). Kick drums and 808s should keep their low-end, but vocals, guitars, synths, and drums like snare benefit from HPF below 80–120 Hz to clear mud and carve space.
Recording environment, microphone type, and source material all affect the kick's inherent frequency content. A bright room with a Shure Beta 52A creates different characteristics than a vintage sample, so the EQ starting points in the cheat sheet are guidelines only—always trust your ears to adjust based on your specific recording.
Boost vocals in the 2–4 kHz presence range to make them sound forward, aggressive, and more intelligible in the mix. This frequency band is also where presence peaks on snares, so be careful with balance when boosting multiple instruments here.
Nasality and honkiness live in the 500 Hz–2 kHz midrange, with the strongest culprit around 800 Hz–1 kHz. Cut in this range on vocals and guitars to remove phone-like, nasal qualities while preserving the instrument's body and warmth.
Presence (2–5 kHz) makes sounds cutting and forward in the mix, while air (10–20 kHz) adds sparkle, shimmer, and breathiness without aggression. Use presence boosts for vocals and snares to cut through, and air boosts on cymbals and vocals for brightness and space.
They need different approaches because kick drums and bass occupy different frequency roles. Boost kick around 80 Hz for punch, but cut bass guitar mud at 150–200 Hz—the same frequencies don't serve both instruments equally since they have different recording characteristics and mix purposes.
