View on KVR Audio

Ignite Amp’s Pro F.E.T. is a digital emulation of a high gain distortion preamp/stomp-box for guitar. It was developed to accurately model its real hardware counterpart, designed and built by Ignite Amps in 2018.

The ProF.E.T. core circuit is capable of delivering a lot of tube-like saturation using carefully tuned JFET-based gain stages and filters to keep the distortion aggressive and rich with harmonics.

Like all the other options on this list, it is free. So take advantage of this, download it, and try it out.


  • Ignite Amps’ proprietary JFET non-linear modeling engine
  • 4 controls tone stack with additional Shape switch
  • Mono and Stereo processing support
  • Selectable oversampling rate (up to 8x)
  • Global input and output level controls


This free VST plug-in from Ignite Amps provides a high gain JFET-based overdrive, with all of the saturation and harmonics you would expect from the real deal.

The tone section has four controls over highs, lows, and high and low mids, with a Shape toggle switch that changes the character of the EQ curve, for added tonal flexibility.

The Pro F.E.T. was not really designed to get low gain sounds, so keep that in mind. It is more of a tight distortion with a fast attack that will be great for guitarists who play metal and other heavy styles.

Ignite Amp’s Pro F.E.T. supports mono or stereo output, and all controls can be automated within your DAW. Additionally, the Pro F.E.T features a 4 controls-based tone stack with 2 different modes that ensure maximum versatility and tone-shaping options.

You can use this VST plug-in as a preamp or a distortion unit in front of a clean amplifier, and it will deliver quality results in both cases.

The Pro F.E.T features a double-precision (64-bit) floating-point mathematical model, fully automatable controls, and Ignite Amps’ proprietary preset management system with bank file import/export functions.

Finally, the Pro F.E.T. features mono and stereo processing support and is compatible with Windows 64/32-bit, Mac VST 64-bit, AU, AAX.

4. Mercuriall Chorus WS-1

Mercuriall Audio Software Chorus WS1

WS-1 is a stereo chorus stompbox based on the classic BOSS CE-2 featuring speed, depth, and mix controls.

View on Mercuriall Audio

The Mercuriall Chorus WS-1 is the only modulation guitar pedal plugin on this list. It is loosely modeled after the BOSS CE-2, the famous blue chorus ensemble pedal.

Launched in 1976, the CE-2 Chorus Ensemble was the world’s first chorus effect pedal and the very first BOSS pedal, and its sound was used for many other iconic pieces of gear, such as the Roland JC-120 Jazz Chorus amp.

The CE-2 has been used by the likes of Brian May, Eric Clapton, and John Frusciante, and was the basis for a legendary sound that defined an era and is still sold today in its original form.

Lucky for us, Mercuriall has created a VST emulation of the CE-2 with the WS-1. Oh yeah, and it’s free!


  • Depth, Speed, and Mix control
  • Modeled after the legendary BOSS CE-1
  • Capable of pitch shifting
  • Can run in mono or stereo
  • Compatible with Windows and Mac


The Mercuriall Chorus WS-1 allows you to control the amount of modulation with depth, and there isn’t much detuning at lower settings. On the other hand, going above 25% starts to introduce pitch shifting, which can add to your sonic palette and increase the usability of this plug-in.

It features a Speed knob that affects the rate of the pitch shift, while the Mix knob sets the overall wet/dry balance. It can run in mono or stereo, and while it’s more on the subtle side of chorusing it adds a dimension that is a great alternative to the chorus plug-ins that come bundled with DAWs.

Overall, it’s a great choice of chorus effect for your DAW, and it’s free! System requirements for the Mercuriall Chorus WS-1 are Windows 64-bit VST/AAX, Mac 64-bit VST, AU, AAX.

The Ignite Amps TSB1 Tyrant Screamer is the second free VST plug-in in this list that is based on the legendary Ibanez Tube Screamer distortion pedal.

However, this one aims to be more of a Tube Screamer flavored distortion for heavier styles of music. So, if you like that iconic Ibanez Tube Screamer sound but play metal or music that requires more aggressive types of distortion, the TSB1 Tyrant Screamer by Ignite Amps might be for you.


  • Tube Screamer vibe for heavier music
  • Familiar three-knob setup
  • Additional sweep control that tailors the midrange
  • Designed specifically for down-tuned guitars
  • Mono or stereo output


The Ignite Amps TSB1 Tyrant Screamer is an overdrive with some Tube Screamer similarities but was designed and built for guitarists that gravitate towards the heaviest genres and music styles.

This free VST distortion pedal plug-in features the familiar three-knob setup as an Ibanez Tube Screamer, but with an additional sweep control that tailors the midrange, allowing you to get that scooped distortion sound that is favored in metal.

It was designed specifically for down-tuned guitars to stay tight and fast with the lower registers. Like the other Ignite plug-ins, it is a meticulously modeled simulation with controls that can be automated, oversampling options, and mono or stereo output.

It is compatible with Windows and Mac 64-bit VST/VST3/AU. This is a fantastic choice for those lovers of the Tube Screamer that play metal or require very aggressive distortion.

6. Heptode Deep Crunch

Heptode Deep Crunch

Heptode is a manufacturer based in Asia that makes hardware and software guitar effects. The Deep Crunch free VST plug-in is based on their analog pedal of the same name.

It emulates a Soldano SLO-100, one of the most popular high gain amps of all time used by the likes of Eric Clapton and Mark Knopfler.

Heptode emulated its own stompbox that was an attempt to emulate the SLO-100. Check out their free VST plug-in stompbox version and decide if it works for you.


  • Modeled after Heptode’s Soldano SLO-100 stompbox
  • 3-band EQ
  • Presented in a stompbox design and operation form
  • Cab Sim switch
  • Gain and level knobs


The Heptode Deep Crunch features a 3-band EQ, gain, and level controls dial in your sound, and you can toggle on and off the onboard cabinet simulation.

Its design features a typical stompbox approach with five knobs at the top with a cab sim switch, a footswitch that activates and deactivates the effect, and in/out quarter-inch ports.

It is based on the Heptode’s Soldanos Super Lead Overdrive 100 (SLO-100) stompbox. This amp set the standard for modern high-gain amplification and remains a popular choice today for those that can afford its price tag.

The Heptode Deep Crunch is great for all styles of rock and plays nicely with basically any source you decide to pair it with. It is compatible with Windows and Mac as a 32bit and 64bit VST.

The overall design of the original RAT pedal is pretty similar to that of the BOSS DS-1 distortion pedal. However, the RAT has a very unique sound that still appeals to many guitarists, almost half a century after its initial release.

And now, you can try it out for free thanks to TSE. What’s not to like?
