3. Creative EQ and making room for the vocal

Complementary EQ: give the guitar character and open a gap in the mids so the vocal is heard without lowering the guitars.

You’ve already cleaned the guitar (section 2). Now creative EQ does two things: it gives it character (more attack, more brightness, more body, depending on what the song asks for) and — key in rock/metal — it opens a gap for the vocal so it’s understood without having to lower the guitars. It’s the difference between a mix where “you can’t hear the vocal” and one where everything coexists.

The problem: guitar and vocal fight over the same mids

The vocal and the distorted guitar occupy the same zone (roughly 1–4 kHz), where intelligibility lives. If they both push there, either the lyrics aren’t understood or you have to lower the guitars so much that the song loses power. The solution isn’t to lower: it’s to share.

Complementary EQ (the central trick)

Where the vocal needs to shine (its presence zone, typically 2–4 kHz), you make the guitar a gentle cut (a wide bell, −2 to −4 dB). The guitar “yields” that space to the vocal. It’s not heard as a hole: it’s heard as the vocal appearing without lowering anything.

Room for the vocal (complementary dip)2–4 kHz · wide bell · −2 to −4 dB · on the guitar

Cutting here on the guitar frees the vocal's presence zone. If you cut too much, the guitar loses attack and moves back; if you cut too little, the vocal keeps fighting. Adjust with the vocal playing.

Boosts that are worth it (with care)

Attack / pick1–3 kHz (slight boost, +1 to +3 dB)

This is where the pick 'click' and the riff's definition are. A touch makes the guitar cut through the mix. Careful: it's the vocal's zone, so boost with judgment (sometimes the opposite is better — yielding to the vocal).

Air / brightness6–10 kHz (slight high-shelf, +1 to +2 dB)

A bit of air up top sounds 'expensive' and open. In metal, be careful not to wake up the fizz you tamed in section 2. A little, with a gentle shelf.

Try out the frequency sharing

Use the playground to hear how a cut in the mids changes the feel of the guitar (more “behind”, leaving room for the center) versus a boost (more “in front”, fighting the center). It’s the same gesture you make for the vocal.

Playground · 3-band equalizer

  • •▶ Play — plays the audio in a loop.
  • •No EQ / With EQ — switch between the sound with and without the EQ to compare, at the same volume. The segment with the lit border is the one you're hearing (the classic studio “A/B” comparison).
  • •↺ Reset — returns the controls to 0.

🎧 Audio to processChoose which sound goes through the effect:

  • •🎸 Bass — a synthesized riff with dynamics: ideal for hearing compression.
  • •📢 Pink noise — an even sound across the whole spectrum: ideal for “seeing” the EQ.
  • •🎵 Load your audio — your own file (MP3, WAV, OGG, FLAC, M4A…); it's processed locally in your browser and isn't uploaded anywhere.

Each control changes one zone of the sound. Move it and listen (and watch the spectrum above move):

LOWS

MIDS

HIGHS

An easy experiment: choose 📢 Pink noise, lower the LOWS Gain (it clears up) and raise the MIDS gain at 3–5 kHz (it gets more present). Switch the EQ on and off to compare with and without.
🟠 Better to set it now· in mixing

Room for the vocal is what most quickly solves the 'you can't understand the vocal' complaint in rock/metal. It's best done in the mix because it depends on the balance with the real vocal, something that didn't exist while recording.

What you should NOT chase yet

Guitar + vocal for the gap demoPending — this one is on you

To show the effect for real I need two audio files from the guide song in prodmus_frontend/public/audio/guitarra/: the rhythm (with amp sim/Helix) and a vocal line over the same passage (even a guide take), WAV 24/48. With both I’ll build an A/B of flat guitar vs guitar with a gap so you can hear the vocal appear without lowering the guitar.

Quick path — make room for the vocal

Quick path

  1. Play guitar + vocal together (not in solo).
  2. On the guitar, a wide bell of −2 to −4 dB between 2–4 kHz.
  3. Adjust the frequency until the vocal 'appears' without the guitar dulling.
  4. If you want more attack, +1 to +2 dB in 1–3 kHz (with judgment, it's the vocal's zone).
  5. A touch of air (6–10 kHz) only if needed and without waking up the fizz.

Expected result

Expected result

A guitar with its own character that coexists with the vocal: the lyrics are understood with the guitars at a good level, without having to lower them. On A/B, the vocal should “appear” when you enable the gap, without the guitar sounding hollowed out. With the frequency sharing solved, you move on to giving it color with saturation.
