The 7 Best Tremolo VST Plugins 2024 | Eventide, SoundToys.. - 2024 Update

In this post, we will be reviewing the 7 tremolo plugins that we consider to be the best on the market in 2024.

In modern music production, Tremolo can be used as an effect to create tonal dynamics around a signal. The phrase has traditionally been associated with bowed string instruments such as violins or guitars but has since evolved to be used loosely in other music areas. In the case of vocals, singers use tremolo to create a quiver over a sustained note. With Tremolo, a note’s pitch stays constant but sounds as though it is moving due to the shift in volume from a note’s repetition.

In a nutshell, here are our picks:

1. BLEASS Dragonfly

2. SoundToys Tremolator

3. Eventide Undulator

4. Goodhertz Trem Control

5. Melda MTremoloMB

6. Kuassa EFEKTOR TR3604

7. AudioThing – Things Motor

With percussion or drums, Tremolo can be used as a rhythmic term to define a rumbling sound caused by soft, fast repetitive drum hits.  Also, the effect has been widely used amongst electric guitar and keyboard players.

A tremolo effect places amplitude modulation on a signal to create volume changes. A signal is sent into a tremolo effect unit and is routed through a low-frequency oscillator (LFO). This LFO causes the signal’s strength to rise and fall incrementally. The result is a wavy or quivery sound effect. 

The lower the frequency of the LFO, the slower the rate of amplitude modulation. There are a few ways to create electronic Tremolo. The electronic effect was believed to have been pioneered by Harry DeArmond, who invented the Model 800 Trem Trol in 1948.

This stompbox was the world’s first guitar effects pedal, and it consisted of a tiny motor that shook a bottle with conductible fluid inside the pedal. The bottle’s shaking motion would cause a signal’s voltage to waiver and thus create a rhythmic, tonal modulation. The bottle that conducts electricity inside the Trem Trol effects pedal is essentially what LFO circuit units are modeled on.

With all that being said, let’s finally jump to the mentioned list; that’s what you came here for!

SoundToys Tremolator Review - 7 Best Tremolo VST Plugins |

Tremolator is a minimal but expansive plugin designed by Soundtoys.

This plugin hosts two straightforward interfaces with a generous selection of rhythmic and dynamic controls for you to experiment with.

The emulators on the Tremolator are based on classic analog gear circuits such as the Fender Vibrolux amp. 

Key Features:

  • Rhythmic Envelope Editor

The rhythmic editor offers you a wide selection of rhythmic parameter controls that they can apply to their Tremolo’s LFO. These parameters include often overlooked parameters of rhythm control, such as groove and accent, and can help you generate some truly authentic volume modulations. 

  • Waveshape Editor

This feature lets you slightly adjust the curve or slope of your LFO waveshape. You can load in preset shapes for editing or design simple LFO patterns from scratch in the editor’s graphic window. The editor also comes with a smoothing function to help remove any glitches or pops caused by the effect’s processing

  • Dynamic Modulation Controls

The second interface on the Tremolator gives you a Dynamic Control menu. Here you can set the threshold, attack, and release of your effect, as well as adjust the Tremolo’s modulation speed and depth. You can automate these parameters or tweak them manually during playback or performance to help create distinct organic modulations. 

Rhythmic Auto-Gating with Tremolator


Soundtoys Tremolator requires Windows & or higher and Mac OS X 10.10 or later. It is available in AAX, AU, and VST versions. 


The Tremolater looks and sounds very much like something designed by guitar players for guitar players. However, the Rhythmic Envelope Editor’s addition makes it a handy tool for anyone looking to create punchy, tight modulations with their Tremolo. This plugin is light on the CPU and links easily with external devices, making it an asset for producers or engineers who use large effects racks.

Eventide Undulator Review - 7 Best Tremolo VST Plugins |

Eventide’s Undulator is modeled on the Tremolo preset that came with their popular H3000 analog multi-fx processor.

The interface will be easy for most guitar players to adapt to as it resembles a stompbox unit. The controls on this plugin are easy to access for real-time use and would suit live performance situations quite well. 

Key Features:

  • Fast/Slow Toggle

This button toggles you between your primary Tremolo and a second set to a slower relative speed. This trigger is excellent for creating unpredictable volume changes in your signal flow. 

  • Spread Parameter

The spread parameter allows you to place harmonics on top of your affected signal for a wider sounding tremolo. You can patch other effects into this one as you would on a modular synth. 

  • Secondary LFO

Beneath the primary controls in the center of the Undulator’s interface are a set of knobs that control a second LFO. This LFO adjusts the depth and speed of your Tremolo and modulates its minimum and maximum values to your taste. 

  • Envelope/ADSR mode

Using this setting on your primary LFO will cause your signal’s modulation to be controlled by its own amplitude. This means that your Tremolo will rise and fall according to the peaks of your input signal. This unique Tremolo feels very organic and sounds excellent over drones, guitars, or synths. 

Eventide H9 Undulator - Tremolator VST Plugin - Review and Walkthrough


The Eventide Plugin is available to Windows 7 and up or OS X 10.12 or higher. It’s available in VST, AAX, or AU formats.


It may not be the best plugin for building meticulous volume modulation patterns or sequences. Still, it can be beneficial for generating modulations that you can tweak on the fly. The addition of the secondary LFO controls makes for very intriguing modulations when patched in with the spread parameters and is ideal for giving signals a dreamy character.

Goodhertz Trem Control Review - 7 Best Tremolo VST Plugins |

Goodhertz has designed the Trem Control in collaboration with Theo Katzman of Vulfpeck fame.

This is evident in the tube-amp style tremolo processing that comes with this plugin, as Katzman’s primary instrument is a Fender Stratocaster. The interface is straightforward on the eyes and features a range of basic digital faders and dropdown menus that give you meticulous control of their tremolo parameters. 

Key Features:

  • 8 Types of Tremolo Presets

Eight standard tremolo settings feature on the Trem Control plugin. You can choose to affect just the lows, mids, or high-frequency ranges. Alternatively, you can set your Tremolo to mid/side processing mode for some extra stereo clarity. Each of the presets is fully adjustable, and you can save your future use. 

  • Vibe

The Vibe fader blends in Trem Control’s signature tube saturation with your tremolo signal and adds some lush color to your output signal. You can push the effect to extreme values to generate shrill harmonic content. 

  • Bias

This dial allows you to adjust the width of the peaks in your LFO cycles. Lower values equate to smaller sharper peaks, whereas higher values create broader slopes with smooth peaks. 

  • Advanced Shaping Feature

This tab is an extended menu that lets you enhance some of your LFO’s parameters. You have the option of setting the phase point in your LFO. There’s also a stereo bias dial, which adds a stereo panning effect to your Tremolo. 

Trem Control — Theo Katzman


Trem Control works with Mac OS X 10.9 or higher and Windows 7 or later. It is available for download as a VST, VST3, or AAX.

Things Motor Review - 7 Best Tremolo VST Plugins |

Motor is more a morphing tool than a tremolo plugin, but that’s what makes it interesting.

The plugin is based on a hardware unit that used a real motor for modulating sound. The relatively simple interface of this plugin houses a rate parameter, wave selection, and more knobs that are straightforward. Turning up the Tremolo parameter at the bottom adds tremolo to your sound.

Key Features:

  • Variable LFO Waveforms

The graphic in the center called “Wave” lets you select from a variety of waveforms to use for your tremolo effect. The shapes range from a simple sine wave and square wave to sawtooth or morphed shapes.

  • Side-Chain Input

Using the side-chain input, you can choose to “tremolo” between two sounds. In other words, it switches between any two inputs at the rate you assign to it. Further, you can control the loudness of either signal using the Balance knob.

  • Easy Toggle

You can turn the effect on or off using the ▶ button labeled Motor at the bottom right. However, since this is an emulation of hardware, the button will slow down the “motor” to stillness or speed it up to the assigned speed. Turning down the Speed knob next to the button will make the button instantaneous.


Motor is available for Windows 7 or higher and macOS 10.9 or higher, both 64-bit only. It comes in VST 2/3, AU, and AAX formats.


This plugin is far more than a simple tremolo effect. Using its other parameters, you can get strange audio modulation and almost granular effects. So, we think it’s a wise investment for the flexibility you will get.

4. Beijaflor TAS-X

More Info & Download

Beijaflor TAS-X Review - The 5 Best Free Tremolo Plugins |

Anyone who is a fan of stereo-based effects will enjoy the TAS-X by Beijaflor.

The plugin is made up of two LFO module generators that you can map and phase to their preference. The TAS-X is lovely if you’re looking for speedy access to a reliable minimalist tremolo effects plugin. 

Key Features:

  • Left and Right LFO-Modules

TAS-X consists of two independent LFO engines that you can configure with a range of shapes or automation. Adding panning to your Tremolo can vastly give it some added stereo dynamics, and you can push these LFO’s to generate some dizzying after-effects. 

  • Independent Dry/Wet Knobs

Most plugins and devices offer you a single dry/wet control to determine the overall strength or depth of that respective effect. The TAS-X features separate Dry and Wet knobs. You can use these to blend your dry input signal with your affected output signal, much like the effects send. This control gives you some added scope when it comes to finding a place for your Tremolo in your overall mix in situations like gain staging. 

  • Smoothing and Limiting Control

The built-in smoothing and limiting controls will help you tame any spikes in amplitude caused by the TAS-X’s processing. You can use the limiter to increase your overall output level without causing any clipping.


TAS-X is available in VST, VST3, and AU formats. Windows Users require seven or higher, and Mac users will need OS.X 10.9 or later.


The TAS-X plugin can be likened to Ableton’s stock auto-pan device with the addition of tremolo processing. Producers and engineers should find the UI relatively easy to navigate and understand, as there are no intense, moving graphics or complex LFO editors with this plugin.

It may not offer you highly in-depth control of their LFO’s or have any added effects like drive or saturation, but the Tas-X will sound great when used in conjunction with other effects units or plugins.

Puremagnetik Clusters

More Info & Price

Puremagnetik Clusters Review - 7 Best Tremolo VST Plugins |

Clusters by Puremagnetik is punted as a harmonic tremolo shaper.

The plugin’s interface has a futuristic aesthetic with a handful of easy-to-use controls that create stunning volume automation.  This plugin is not only minimal in its design. It’s also relatively light on CPU despite its fast and reactive processing speed. 

Key Features:

  • Crossover

The Crossover knob on the Clusters plugin lets you choose how much of your input signal’s low and high frequencies are affected by your Tremolo. This handy feature divides your signal into two and plays them back together at slightly fluctuating speeds. 

  • Overclock

You can use this setting to either multiply or divide your Tremolo’s LFO speed. Higher settings produce harmonic overtones or ring modulations. This knob is not confused with the Rate control on the plugin, which sets the tremolo speed at quantized values. 

  • Animation Parameter

You can adjust this setting to either have the crossover’s frequency response stagnant or modulate. This means that your Tremolo will shift up and down your signal’s frequency spectrum, creating some added motion dynamics to your input signal. 

Clusters | Harmonic Tremolo Shaper


This plugin works exclusively with Windows 10 and Mac OS X 10.8 or higher. You can download it in either VST or AU formats. 


The Clusters tremolo plugin is very well suited to producers who prefer dials and knobs over envelope editors and step sequence controls. The plugin interface is very intuitive, and the Clusters plugin comes with presets that range from smooth and subtle to harsh and avant-garde. 

What Does A Tremolo Sound Like?

The rapid signal fluctuations created by tremolo devices generate shivering or trembling audio effects. The effect can translate differently depending on the type of tremolo device you are using and the parameters you set on that respective device. 

The shape of a waveform in a tremolo’s LFO will determine the effect’s primary characteristics. 

Here’s a quick rundown of how the most commonly used tremolo waveshapes sound:

  • Sine

Selected for its subtlety, a sine-wave tremolo produces very smooth and coherent oscillations in volume. At maximum value, its effect can enhance the blend of a signal due to its modulating properties’ gentle nature. 

  • Triangle

The triangle wave is the most commonly used tremolo waveform among guitarists. The shape is featured in many guitar amplifiers and stompbox units and is revered for sounding distinct without being overbearing. The volume modulations generated by this shape are more rigid than a sine wave but still maintain a semblance of fluidity. 

  • Square

This is the most obtuse of the three tremolo waveforms. A square-LFO generates a very choppy oscillation around a signal, with more defined slopes between each peak and dip. The effect is likened to turning the signal on and off and produces a shuddering sound at high values. 

Tips and Tricks for using Tremolo

  • While the tremolo effect is traditionally used for guitar, it can sound amazing over many other instruments that share the same frequency range or timbre, such as strings, organs, or even vocals. 
  • When setting your Tremolo, solo the track that you affect and listen to it with the metronome. Much like bass or drums, this effect can have a rhythmic sweet spot, and you want to try and get your Tremolo to groove with your click track. Sometimes this will mean setting the rate and speeds manually instead of using quantized values.
  • Remember that with effects, less is often better than more. You want to make sure that you don’t land up intruding on other mix elements with your Tremolo. When setting the depth or dry/wet levels, start with small amounts and work your way up until you hear something clash, then back the effect off until it sits neatly inside your mix. 

As with most LFO based effects units, there are some oscillation parameters you can adjust while using a tremolo effect. 

  • Depth

Depth will determine the overall range between peak points of your signal’s modulation. This parameter can also be used as an alternative to a Dry/Wet Knob on tremolo effects. 

  • Shape

Oscillators can perform in different waveshapes to produce distinct modulations on a signal. The most commonly used wave shapes are Sine, Square, and Triangle. Sine and Triangle are generally identified as the smoother of these shapes, while saw and square can create more abrasive tones. 

  • Rate

Most tremolo effects have a control that allows you to set the speed of the LFO. These modulations can either be assigned to a quantized rate or at a Hz rate of up to 25Hz on average.


Tremolo can be a potent tool when used in the right context. There are several tremolo plugins listed above that should suit most types of audio requirements and ambitions. If you’re looking to explore the depths and possibilities of this effect, we recommend trying the Trem Control by Goodhertz, Tremolator or the MTremoloMB by Melda.

If you’re looking for a tremolo plugin that is light and simple, give the Efektor by Kuassa audio a shot. Thanks for taking the time out to read through our list of the top tremolo plugins of 2024. We hope this article left you ready to explore and inspire!
