5 Real Mixing Techniques for Muddy Guitars, Keys, and Vocals From a Live Session
What's Included in This Guitar, Keys, and Vocal Mixing Breakdown?
This is the second half of a two-part mixing session on Liza Colby's rock single "My World," using only Black Salt Audio plugins. In part one, the drums and bass were built with Telos Drums, Telos Bass, and the Black Salt Audio drum bus compressor. This second session finishes the song: rhythm and lead guitars, two organ parts, lead vocals, and a light pass of master bus processing.
None of this depends on owning that exact plugin bundle. Every technique below, dialing in a muddy guitar mix with one preset, repurposing an EQ plugin on a part it wasn't built for, chaining EQ, de-ess, and saturation on a vocal, borrowing reverb out of a delay plugin, and adding subtle master bus warmth, works with whatever EQ, saturator, and delay plugin already sit in your own DAW.

1. How to Fix a Muddy Guitar Mix (Without Overdoing the Saturation)
The rhythm guitars for "My World" came in through Telos Guitars with no adjustments yet, straight off a gain-staged, phase-aligned DI track from the prior session. Listened to in bypass, the verdict was immediate: the guitar tone was dark and muddy, the exact complaint that sends most home-recording mixers hunting through a dozen EQ bands.
"Kind of dark, kind of muddy." [3:07]
Instead of building an EQ curve from scratch, the fix came from Telos Guitars' preset browser. Under the "Mid Gain" category sits a preset literally called "Bright and Upfront," and applying it to guitar one left instantly cut through the mud, adding top-end clarity and presence without piling on gain. The second rhythm guitar (panned hard right) got a different preset from the same browser and was tucked in just as fast.
Once both rhythm guitars were panned hard left and right with guitar two up the center, the plugin's Drive Control and Saturate knobs came into play, and here the setting mattered as much as the preset choice. Because the center guitar part was already a distorted tone straight from the amp, the Saturate knob was deliberately kept low. Stacking more plugin saturation on top of an already-driven guitar just adds mush, the opposite of what a muddy guitar mix needs.
Try This In Your Own Mix
Before reaching for a parametric EQ on a dark or boxy guitar, scroll through your plugin's preset list for anything labeled "bright," "presence," or "mid gain." A well-built preset gets you most of the way there in one click, and you can still fine-tune from that starting point instead of from zero.
If a guitar part is already distorted at the source, treat any saturation knob on your mixing plugin as a "less is more" control, not a "more is better" one. If you want a lighter-weight way to start applying moves like this without committing to a paid course yet, the free 90-minute mixing course covers this same kind of preset-first workflow using only stock plugins.
2. How to EQ Keyboards and Organs When You Don't Have a Dedicated Plugin
"My World" has two organ parts, a B3-style organ mid-song and more of a church organ near the end. The catch: Black Salt Audio doesn't make a dedicated keys or organ plugin. Drums, bass, guitars, and vocals all had a purpose-built Telos plugin waiting. Keyboards did not.
Rather than skip processing altogether or force a guitar plugin onto an organ part, the call was to reach for Instinct EQ, a general-purpose Black Salt Audio EQ plugin that had never been used on this session before.
"I've never used this. Let's try it. Why not?" [10:46]
Instinct EQ splits into two sections: a straightforward High/Mid2/Mid1/Low EQ on the left, and a "Surgery" section on the right for more targeted, narrow-band notching. The plugin also has a Vibe Select toggle between "Clean" and "Analog" tone-shaping character. For the organ, Analog was the obvious choice, adding a touch of harmonic warmth on top of the EQ moves rather than leaving the signal sterile.
The broader lesson generalizes past this one plugin: when a mixing suite (or a stock DAW bundle) doesn't have a dedicated tool for the instrument in front of you, a solid general-purpose EQ with a bit of built-in character can cover the gap. An organ, a synth pad, or a piano doesn't need its own named plugin to sound finished, it needs the right kind of tonal shaping, and a general EQ with a saturation or vibe mode built in can supply both at once.
Try This In Your Own Mix
Next time a keyboard, synth, or organ part doesn't have an obvious plugin match, try your favorite general EQ plugin instead of skipping processing. If it has a saturation, drive, or "vibe" mode, toggle it on before you touch a single band, character first, surgical EQ second.
3. A One-Preset Vocal Chain: EQ, De-Esser, and Saturation Together
Lead vocals for the verse and chorus went through Telos Vocals, and the fastest way to hear whether the plugin could handle a rock-leaning female vocal was to solo the track and load the "Female Popstar" preset as a starting point.
What makes that single preset worth studying is what it's actually doing under the hood: a Low/Mid/High EQ section, a de-esser, and a saturator all running in the same signal path, all dialed in together instead of stacked as three separate plugins.
"We have a basic EQ up here with a de-esser, which is great. Saturator." [15:17]
That EQ-then-de-ess-then-saturate order matters. EQ shapes the overall tone first, so the de-esser is reacting to the vocal's final tonal balance rather than an unshaped signal, and only after both of those does saturation add harmonic thickness on top of an already-controlled vocal. Loading them as one preset instead of three separate plugin instances also means the whole chain is gain-staged to work together out of the gate, rather than three plugins fighting each other's output levels.
The takeaway isn't "buy this exact plugin." It's that a vocal chain built in that EQ-then-de-ess-then-saturate order, whether that's three separate plugins or one channel strip, gets a rough vocal to a usable place faster than reaching for compression first.
Try This In Your Own Mix
If your vocal chain currently starts with compression, try reordering it: EQ first to shape tone, de-esser second to tame sibilance on that shaped tone, then saturation last for harmonic glue. It's a small reorder that changes how much work each plugin has to do.
Building a chain like this from scratch is exactly the kind of decision walked through step-by-step, with feedback on your own mixes, inside The Mixing Academy.
4. How to Turn a Delay Plugin Into a Reverb (And Reuse It on Guitars)
BSA Delays went on the lead vocal first, set to a subtle, low-in-the-mix repeat rather than anything rhythmic or obvious. But the more interesting move came afterward, when that same delay instance got dragged onto the guitars for a completely different job: adding space, not slap-back.
BSA Delays has a small set of controls, including Feedback, Reverb, and Drive knobs alongside Low Cut, Size, and High Cut. To turn a delay into a usable reverb-only effect, the delay-specific character (Drive) gets pulled down while the Reverb knob stays up.
"What if I were to turn all this down, turn down the drive? I just want the reverb portion of this." [20:36]
With the drive backed off, what's left is a soft wash of reverb space with none of the delay plugin's repeat character fighting for room. That reverb-only signal, panned back to center and blended in subtly on both rhythm guitars, gave the guitars a sense of depth without pushing them further back in the mix than intended.
This is a genuinely useful trick if your plugin folder is light on dedicated reverbs: almost any delay plugin with a built-in reverb or "size" control can be coaxed into acting as a standalone reverb by minimizing everything that makes it sound like a delay and keeping only the reverb-specific control up.
Try This In Your Own Mix
Open a delay plugin that has a built-in reverb, drive, or saturation control alongside its delay time and feedback. Turn everything delay-specific down to zero, keep only the reverb control active, and use it as a send for adding subtle space to a guitar, keys, or backing vocal part.
5. How to Add Warmth to Your Mix on the Master Bus (Without Losing Clarity)
The final processing move on "My World" happened on the master bus, using a plugin outside the Black Salt Audio catalog: Baby Audio's Reviver, an enhancer plugin with simple Low, Mid, and High controls. Its "Master Warmth" preset was loaded up mostly out of curiosity, since the plugin's exact function wasn't fully clear going in.
"It's kind of an enhancer... You want to use this kind of subtle. We want this kind of subtle." [19:48]
That last line is the whole lesson. Master bus warmth processing is meant to be felt more than heard, a little added density and low-mid glow that ties the mix together without anyone in the room being able to point to exactly what changed. Pushed too far, the same plugin can start smearing transients and thickening the mix into mud, undoing everything the guitar and vocal work upstream just fixed.
The practical test: A/B the master bus processing in and out at the loudest section of the song. If the "in" version sounds noticeably louder, warmer, or bigger in a way that's obviously describable, it's probably set too high. If it just feels a little more finished without an easy one-word description, that's the subtle zone this technique is aiming for.
Try This In Your Own Mix
Load any warmth, enhancer, or tape-style saturation plugin on your master bus and find the setting that sounds good to you. Then cut that setting roughly in half. Master bus warmth almost always reads as "too much" before it reads as "just right."
What Worked, and What to Watch For
What Worked
- Reaching for a labeled preset ("Bright and Upfront," "Female Popstar," "Master Warmth") first, then tweaking, instead of building every chain from a blank slate.
- Holding back saturation on a guitar that was already distorted at the source, instead of stacking more drive on top by default.
- Reusing one delay plugin's reverb section on guitars instead of loading a second, dedicated reverb plugin just for that job.
- Applying an EQ plugin never used before on this session (Instinct EQ) to a part with no dedicated plugin option, rather than skipping processing.
What to Watch For
- Not every plugin ships a preset this well-matched to your source material. Presets are a fast starting point here specifically because Black Salt Audio's are broad and musical, treat them as a draft, not a finish line.
- The reverb-from-a-delay trick depends on your delay plugin actually having a built-in reverb or size control. Not all delay plugins do.
- Master bus warmth settings that sound great soloed on the loudest chorus can sound overcooked once the whole arrangement, including a busy verse, plays back. Always check both.
Frequently Asked Questions
1) How do I fix a muddy guitar mix without adding more EQ moves?
Start with your plugin's preset browser before touching individual EQ bands. A preset built around "bright," "presence," or "mid gain" language is often tuned to cut the same low-mid buildup that makes a guitar sound muddy in the first place, and it gets you most of the way there in one click.
2) How much saturation should I use on an already-distorted guitar?
Very little. If the guitar is already driven at the amp or pedal level, treat any plugin saturation or drive knob as a fine-tuning tool rather than a tone-shaping one. Adding more saturation on top of an already-distorted signal usually just adds mud instead of character.
3) Can I use an EQ plugin on keys or organ if I don't have a dedicated keyboard plugin?
Yes. A general-purpose EQ, especially one with a built-in saturation or "vibe" mode, can shape an organ or keyboard part just as effectively as an instrument-specific plugin. The instrument doesn't need a plugin with its name on it, it needs the right tonal shaping.
4) What order should a vocal chain go in: EQ, de-esser, then saturation?
EQ first to set the overall tonal balance, de-esser second so it's reacting to the vocal's final tone rather than an unshaped signal, then saturation last to add harmonic thickness on top of an already-controlled vocal. This order shows up in single-plugin vocal chains like Telos Vocals for exactly this reason.
5) How do I add subtle warmth to my mix without losing clarity on the master bus?
Dial in a warmth or enhancer plugin until it sounds good soloed, then cut that setting roughly in half before committing. Warmth processing should be felt, not identified, if you can describe exactly what changed, it's probably set too aggressively.
6) Do these Black Salt Audio techniques still work if I don't own their plugins?
Yes. Every move here, preset-first guitar EQ, saturation restraint on distorted tones, repurposing an EQ on an unsupported instrument, EQ-de-ess-saturate vocal chain ordering, and reverb-from-a-delay, is a general mixing principle. Black Salt Audio's plugins are simply the tools used to demonstrate it in this session.
Quick Recap
- Fixed a muddy guitar tone with the Telos Guitars "Bright and Upfront" preset, keeping saturation low on the already-distorted center guitar.
- Repurposed Instinct EQ, in Analog vibe mode, to shape organ tone with no dedicated keys plugin available.
- Built a full vocal chain, EQ, de-esser, saturation, from Telos Vocals' single "Female Popstar" preset.
- Turned BSA Delays into a reverb-only effect by cutting Drive and keeping Reverb up, then reused it on guitars for space.
- Added subtle master bus warmth with Reviver's "Master Warmth" preset, kept deliberately understated.
Final Thoughts
None of these five moves took more than a couple of minutes to dial in, and that's the actual point of this two-part series: how fast a mix can go from rough multitracks to a finished, cohesive song when the plugin choices are simple and the ear is doing the real work. If you're staring at a muddy guitar, an unsupported keyboard part, or a vocal that needs three plugins' worth of help, start with a preset, trust your ears over the settings, and keep the master bus processing quieter than you think it needs to be.
