The plugin almost wholly replicates the appearance of the actual head. The creators slightly modified the chain by adding a Contour knob to get a more scooped tone and additional Boost overdrive stage. In addition to that – a built-in Marshall cabinet impulse with Celestion V30 speakers.

Among the number of plugins, there are some based on Freedman, Mesa/Boogie, Diezel, and many other brands. Among them is Amplex, a Multiamp that can be all these heads at once.

This virtual amplifier comes with a folder with text documents with the code, which you can load into the plugin. These are the emulations of different guitar amplifiers – a total of more than 20. The list includes amps based on Peavey 5150, Engl Savage, Orange OR120, Mesa Mark II, Diezel VH4, Randall Satan, Marshall JCM800, Bogner Ubershall, and Soldano SLO.

It is important to remember that NaLex software only comes as an amp sim head. It means that you will need to use your own IR loader and a noise gate to get the finished guitar sound.

3. SoftAmp – PSA Review

More Info & Download

If you are a fan of virtual preamps like the legendary SansAmp, this one will pleasantly surprise you. It is the SoftAmp PSA, and it’s completely free.

SoftAmp’s PSA is a virtual-analog guitar preamp, which, unfortunately, is only available for Windows. This plugin has five stages of distortion, complete with a noise gate and compressor. In short, everything you need to get an expressive guitar tone that shines through in the mix.

It is noteworthy that each overdrive stage in the plugin has a specific frequency shaping according to their names. For example, Buzz is responsible for low-end overdrive, Punch for mids, and Crunch overdrives the high frequencies. In addition to the main controls, two more knobs are accountable for the speaker parameters simulator – Shape and Rolloff. If both are set to 0, the speaker simulator is completely bypassed.

Key Features:

  • Asymmetric and Soft-Clip
    These buttons give you even more control over the gain structure. Asymmetric saturates the signal with harmonics, and Soft-Clip makes the distortion less sharp and helps fading notes sound smoother.  

  • PSI Denoiser
    The PSI Denoiser is a noise gate with adaptive release time
    . It is equipped with the Learn function. It means that without playing anything on your guitar, it will detect the noise level itself and provide the appropriate threshold.

  • Squeezo Range compressor
    This compressor is not linear but a musically sounding one. You can use it as both an upward and downward compressor depending on the gain and bias setting.

Compatibility:

The plugin is available for Windows XP or higher 64-bit only. It comes in VST format.

Summary:

It is a great free plugin if you are a Windows user and want something similar to the famous SansAmp. The obvious advantage will be the different stages of distortion, which are responsible for different frequency spectrum ranges. Also, here there are such good things as an adaptive noise gate and compressor. This software is suitable for working with both guitar and bass.

4. EXE Consulting – Classic Thirty Review

More Info & Download

The following free plugin on our list is quite simple but has pretty extensive functionality. It is Classic Thirty by EXE Consulting.

Classic Thirty is also available for Windows users only and emulates the famous Vox AC30 combo amp. This plugin has many effects, a speaker section, a compressor, a separate graphic EQ, and more.

It’s an all-in-one plugin that can provide you with a great classical guitar tone for free. And we’re talking about both clean and overdriven sounds. In the developer’s words, the plugin has accurate circuit modeling and stereo capability, but it uses some CPU.

Key Features:

  • Width control
    This knob allows you to increase the stereo width of the sound field dramatically. You can quickly get dubbing of the left and right rhythm sections from a single DI recording with the width control.

Compatibility:

The plugin is available for Windows 64-bit only. It comes in VST format.

Summary:

If you want to get a pretty good emulation of a Vox AC30 combo with lots of effects and features for free, this plugin can serve you well. It has everything you need to get a finished guitar sound. But the disadvantage will be its use only for Windows and the limited number of available formats.

5. GuitarML – Chameleon Review

More Info & Download

You can also pay attention to this free plugin, Chameleon from GuitarML, as it is straightforward and has three channels.

The Chameleon is a virtual vintage-style amp type head that has three channels. Green will give you a clean tone, and Gold means crunch and Red for a heavier distortion. The interface here is as simple as possible. On the left are the channel selector and the gain control. Then you will see all the usual knobs like Bass, Mid, Treble, Presence, and Master.

It is essential to know that this is only an emulation of the guitar head. Therefore, you will need to use your own IR loader and a noise gate to get the finished guitar sound.

Key Features:

  • RTNeural engine
    The core of the Chameleon plugin sound is a neural network engine that allows the plugin to masquerade as a high-end tube amplifier. This software uses the modern RTNeural engine, which reduces CPU usage.

Compatibility:

The plugin is available for Windows 7 or higher (32 or 64-bit), and macOS 10.11 or higher. It comes in VST3, AU formats, and as a standalone host.

Summary:

A vintage virtual head with three channels is how you can characterize this plugin. It is as easy to use as possible but requires additional software to get the sound ready. So if you’re new to building your guitar circuit, it can get a little tricky to use.

Bonus

Mercuriall Audio Software – Tube Amp U530 Review

Another excellent work from Mercuriall that we decided to put as a bonus on our list. It is the Tube Amp Ultra 530.

The Russian company Mercuriall Audio Software constantly surprises you with its products of incredible quality. The U530 is no exception here.

Mercuriall used the most realistic modeling here. The Tube Amp Ultra 530 is a complete digital replica of the E530 preamp. It means that no waveshapers or equalizers were used in its construction. In addition, the U530 has additional features like a stereo chorus and a cabinet section.

Mercuriall Audio Software - Tube Amp U530 Review - Top 10 Guitar Amp Plugins (And 5 Best FREE Guitar Amps) | Integraudio.com

Key Features:

  • Preamp section
    Here, you will choose between the Clean, Crunch, Soft Lead, and Heavy Lead channels
    . You also have a 3-band EQ for Clean and Crunch and a 4-band EQ for Soft and Heavy Lead. Plus, you can switch between 12AX7-RCA, 12AX7 Tung-Sol, and 12AX7-RSD tubes.
  • Amp section
    This Class A tube amplifier is based on a 6V6 pentode with a feedback loop and Presence control
    . A remarkable feature here is that the power amplifier section considers the cabinet’s resonance properties. It means that if the cabinet simulation is disabled, the power amplifier section operates in neutral mode, allowing you to use your own IRs.
  • Cab section
    The IRs here are assembled from the world’s top-notch cabinets
    . For example, the plugin uses Bogner Uberkab 412, Marshall 1960B, and MESA/BOOGIE 412 RECTIFIER based responses with CelestionV30, JBL K120, and Greenback speakers. Mercuriall used a Shure SM57 microphone to capture all these impulses.
