Evertone Project Bundle v2 Review: Japanese Audio Plugins

Hello! This is Jooyoung Kim, an audio engineer and music producer.

As I told you in the last post, I’ll resume the audio/virtual instruments plugin review. Today, as part of this series, I’d like to talk about the Evertone Project’s plugins.

On the internet, I found that the Evertone Project team is a combination of guitar artisans, studio owners, and audio programmers. In early 2026, they released a few plugins, which are included the Evertone Project Bundle. It contains Expander v2, Compressor v2, Metro v2, MORG Vintage 81, MORG-81 EQP3, and MORG AMP 5A.

While testing these plugins, I was truly impressed by how much effort was put into the MORG series to capture the original hardware’s frequency response. Additionally, the compressor and expander clearly showed a deep consideration for a beat and timing.

By the way, the plugins shown in this post were provided by Plugin Boutique in NFR (Not For Resale) form. Also, if you purchase the plugins through the links in this post, I will receive a small commission that helps me keep this blog going.

Let’s start!


Evertone Compressor / Expander

The Evertone Compressor is an exceptionally transparent tool. While real hardware compressors typically feature non-linear compression action that generates harmonic distortion, each mode (it has four different modes) in this plugin delivers remarkably clean dynamic behavior.

The knobs are quite small, but thanks to its Live Mode, they can be adjusted intuitively.

During my testing, it became clear that this plugin aims for extreme transparency. By offering tempo-synced attack and release parameters, it allows you to control dynamics without adding coloration or breaking the groove. Given the omission of a sidechain input and the inclusion of oversampling, I believe it was designed primarily for final mix bus polishing or grouping stems together.

I feel it would work exceptionally well for classical music, as well as for jazz tracks with a steady, locked-in tempo rather than rubato performances.

These strengths shine through not only in the compressor, but also in the expander.

Generally speaking, an expander isn’t typically used on pristine sources. It’s usually reserved for tracks with background bleed or those that need lost dynamics restored.

If you need to recover dynamics on a stereo track that locks to a specific BPM, I would highly recommend this plugin. Its tempo-sync capability is particularly strong; while the processing might sound a bit unnatural when listened to in solo, it gets nicely masked in context because the dynamic changes fluctuate in rhythm with the BPM.

To be honest, the Plugin Boutique manager originally pitched the idea of framing this as a direct comparison between Sonnox and Evertone.

But during testing, it became clear that they serve fundamentally different purposes. In fact, combining them yields far better results than pitting them against each other: Sonnox handles the tonal character and loudness enhancement, while Evertone delivers transparent bus control and tempo-synced dynamic restoration.

Sonnox’s Inflator and Limiter remain undeniable classics from the era of the Waves L2. That said, when compared to modern processing standards, driving them heavily for raw sound pressure can lead to subtle digital break-up.

To avoid this, setting up a transparent comp upstream to tame dynamic peaks is standard industry practice. This is precisely where the Evertone Compressor shines. It delivers a level of transparency that surpasses native DAW compressors, and yields an even cleaner drop-off than FabFilter Pro-C2 in Clean mode.

Through continuous testing during this review, I’ve found that pairing Evertone’s transparent control with Sonnox’s character creates an incredibly refined signal chain—particularly tailored for acoustic, classical, and jazz genres.

Using them together like this works remarkably well. Compared to other compressors, Evertone introduces far less harmonic coloration—which is presumably why the signal holds up so well without breaking up when pushed into the next stage.


MORG AMP 5A

The naming is quite clever! LA-2A + LA-3A = LA-5A… 🙂 As the name suggests, it seems like an emulation of the Teletronix LA-2A and LA-3A. However, it doesn’t actually have a compression function.

At first glance, I was deeply impressed by this plugin. The sound is quite similar to my Stam Audio SA-2A hardware. It slightly emphasizes high frequencies and brings any audio source to the front of the mix. If it goes on sale, I highly recommend picking this up for LA-2A style saturation.

The frequency response changes dynamically depending on the input level. As you can see, it isn’t smooth and clean like what other companies’ plugins typically show—it has that raw, irregular curve just like real hardware.

This is the 3A’s frequency response. Its output level is also different from that of the 2A.

In 2A mode, there is a gentle compression (or possibly soft clipping) at high signal levels.

The 3A mode also shows a similar trend, but it is much more subtle.

The 2A mode features gentle harmonic distortion. In contrast, the 3A mode has a more aggressive sound.

This plugin is not currently available on Plugin Boutique, but I will add the affiliate link once it goes live.


MORG Vintage 81

The MORG Vintage 81 is a digital clone of NEVE 1081 preamp.

The frequency response also changes based on both the input level and the channel number.

There is a slight compression or level loss at high signal levels.

I was really surprised when I checked the oscilloscope. It showed a very similar behavior in this test.

It isn’t a plugin that blows you away immediately upon insertion. Since the high frequencies can be a little prominent, polishing the top end with a subtle EQ move makes the underlying texture sound much better.

You can take a quick look through the link above.


MORG 81EQP3

As you can tell from the name, it models the Pultec EQP-3 EQ. While there isn’t a vintage Pultec at the school where I teach, I do work with a Tube-Tech EQP-1A there. Surprisingly—and contrary to common belief—the physical hardware exhibits almost no high or low-end frequency loss.

In contrast, the MORG 81EQP3 slightly attenuates the low end and softens the top end upon insertion, giving it a gentle, rounded tone that I feel is tailor-made for jazz.

Wrap Up

The Evertone plugin series is genuinely impressive. You can clearly see the dedication that went into modeling the MORG series, and the LA-5A made me stop and go ‘Woah….’ the moment I inserted it on a track.

Achieving this level of clean, transparent dynamics processing is by no means an easy engineering feat. Having the Evertone Compressor in your toolkit is ideal for placing right before final loudness processing—like Sonnox Inflator or Limiter—to ensure a pristine mix bus.

That’s all for today. See you in the next post!

DIY Audio Project #1 | Tube Saturator with Baxandall EQ (Part 1): Concept and Implementation in Digital

Hi! This is Jooyoung Kim, a mixing engineer and music producer. In the previous post, ‘Wrapping Up 2025‘, I mentioned that I was developing circuits for my personal audio hardware.

Now that the circuit design and simulation are finished and the components and PCBs have been ordered, I am writing this post to record the process—including the failures and successes along the way. To be honest, since the build isn’t finished yet, I can’t guarantee it will be a 100% success.

However, I thought it would be a great opportunity to share what is actually needed for the design process, starting from scratch. I want to explain things in a way that anyone, even those with zero prior knowledge, can easily follow along.

Let’s start!


Concepts

I really love the analog “tube” sounds. However, I don’t have any stereo tube saturator hardware. Also, I don’t have an EQ that can be used for mastering either.

Therefore, I decided to make a stereo tube saturator with Baxandall EQ!

I used KiCad for this project. I highly recommend it because it allows you to seamlessly transition from circuit design to simulation, and finally to PCB layout. But that also means… once you’re done with the circuit, you still have two massive tasks waiting for you (hahaha…). I honestly had no idea what I was getting into until I finished the initial design!


Tube Parts

I already have two tubes (JJ Electronics’ ECC83) that were replaced from my Stam Audio SA-2A, so I wanted to use them for this project. Since I intend to use this gear in the mastering process, I decided to use just a single tube to drive the gain after the input stage.

I also designed the tube stage with adjustable ‘ASYMMETRY’ and ‘DENSITY’ parameters.

ASYMMETRY (Bias Adjustment) parameter controls the grid bias (+/-1V spans in my circuit)) of the vacuum tube. By shifting the bias point, it allows the waveform to clip asymmetrically, which generates even-order harmonics.

DENSITY (Saturation & Body) parameter adjusts the amount of feedback at the cathode stage. By controlling the effectiveness of the bypass capacitor, it pushes the tube to hit its saturation point harder or softer.

To develop this parts, I utilized Gemini (the free version) and referenced the manual of the Wave Arts Tube Saturator Vintage plugin for inspiration. Even though I majored in physics, it’s a field of pure science focused on fundamental principles, so I didn’t really cover practical applications like circuit design. As I mentioned, I actually had very little in-depth knowledge of electronic circuits starting out. But those tools were a huge help! Seriously, use AI tools—they can bridge the gap!


Baxandall EQ Parts

The EQ design is straightforward, consisting of two sections: Low and High. While the gain is continuously adjustable, I made the frequency switchable using rotary switches, allowing for precise and repeatable settings.

Baxandall EQ circuits are quite simple and well-documented, so you can easily find various schematics online to use as a reference.


Input & Output Parts

The input stage was simple enough, but the output stage was a total ambush. I wanted to include a Mix knob, a Mix Bypass switch, a Total Bypass switch, and an Output Gain knob. Trying to integrate all these features into the signal path turned into a bit of a mess!

After completing the overall design, I realized a crucial detail: every single stage had to be in the same phase! If the phases didn’t match, the Mix knob would be useless. So, I had to go back and triple-check the phase of every section after all the work was seemingly ‘done.’ I’ll talk more about this in my next post about the simulation process.


Power Parts

To ensure this hardware works in various environments, I included an adjustable voltage switch(220V-110V) in the power circuit. Since the design requires multiple voltage rails—250V, ±15V, +80V, +12.6V, and ±1V—I had to use a complex, custom-spec toroidal transformer. Managing all these different power requirements in one unit was quite a challenge!

Heat dissipation was a major concern for this build. I basically tortured Gemini with endless questions, forcing it to crunch the numbers until I was sure every component could handle the thermal load.

I’d like to dive deeper into the phase issues and buffers that need to be considered in the simulation, but it would make this post way too long. So, I’ll cover those in the next one.

See you then!
