The Final Clean & Crunch Reference

VirgoTwin is a software simulation that brings to life one of the most iconic American clean amplifiers of the mid-’60s, faithfully capturing its shimmering clarity, immense headroom, and musical dynamics — while adding the flexibility and precision of modern digital engineering.Built around four independent circuits, VirgoTwin offers a wide tonal palette that ranges from pure, glassy cleans to harmonically rich vintage textures.

NORMAL Channel — Pure American Clean

The NORMAL channel delivers the wide-open clean tone that made this style of amplifier a studio and stage staple.Expect:
  • Huge headroom with minimal breakup
  • Bold low end, airy highs, and a scooped midrange
  • Touch-sensitive response that stays articulate even with complex chords
Perfect for maximum clarity and as a rock-solid foundation for pedals.

NORMAL Deluxe Mode — Classic Clean-to-Crunch

Activating Deluxe mode reshapes the channel, shifting toward a warmer, more mid-forward vintage character inspired by smaller American combos of the same era.You get:
  • Earlier and smoother breakup
  • Richer mids and sweeter highs
  • More intimate and organic feel
Ideal for edge-of-breakup tones with a distinctly vintage attitude.

VIBRATO Channel — Added Gain, Reverb & Modulation

The Vibrato channel mirrors the classic clean voice but introduces an additional gain stage, adding presence, harmonic bloom, and dynamic richness when pushed.It also integrates two Spring Reverb types:
    • Basic – Shorter, tighter, more restrained
    • Standard – Fuller, longer, more immersive
Both can operate in mono or stereo. A built-in Tremolo is also included, with four types: Sinusoidal, Triangular, Exponential and Optical.

VIBRATO Deluxe Mode — Vintage Crunch & Harmonic Bloom

Deluxe mode further reshapes the channel, inspired by classic American combos known for dynamic crunch and expressive midrange.You get:
      • More pronounced breakup
      • Spongier and more reactive feel
      • Rich harmonic saturation
Perfect for blues, roots, and classic rock tones. Reverb and Tremolo remain fully available.

 

 Non-Plus-Ultra Preamp

Non-Plus-Ultra Preamp represents the perfect approach to circuit modeling. VirgoTwin preamp features a built-from-scratch 64-bit engine which is based on general purpose hi-quality algorithms and the most recent non-linear models. Special care has been taken in defining the Non-Linear Solver to ensure maximum quality and realism, without losing details in favor of performances (Double-Precision Non-Linear Computing).

Our Non-Plus-Ultra reproductions bring a completely new philosophy to the table: being able to shape your tone by giving total access to the circuit components. Managing each gain stage level, shaping the tone-stacks or modifying the tubes characteristics: there is virtually no limit to what you can achieve with our plugins!

 

Power Amp Distortion & Headroom

The HEADROOM section lets you shape the behavior of the power stage, from clean headroom to full saturation.

You can define how and when the power amp starts to distort, choose different clipping characters, and adjust the interaction between pre and post gain stages.

 

Pwr/Cabs: Non-Linear Convolution

Before describing our solution, let’s talk about what everyone else does: the commonly spread approach of the “single IR” to reproduce a cabinet is nothing more than a digital clean equalizer. Which means: non-linearities are not reproduced at all. Competitors generally model power amps to introduce harmonic distortion, but they totally omit the non-linearities coming from the speaker, the microphone and the mic preamp. While these can be considered somehow negligible for some types of high wattage speakers when dealing high gain sounds, it is essential when the speaker breaks up. Furthermore, sometimes solid state power amps are used to sample cabinet, speakers and mikes, but these power amps, despite being considered “neutral”, have their own “footprints” due to the different impedance, so the interaction with the speaker is noticeably different when compared to a classic tube power-amp.

Another limit of many well-known amp simulations is the complete absence of power amp clipping.

As DiBiQuadro we implemented our own version of Non-Linear Convolution (NLC) to reproduce all the final stages of a miked amplifier. We use to call Pwr/Cab a chain made of:

  • a tube power amp
  • a cabinet/speaker
  • a microphone
  • and a high-end studio preamp
 
This chain is sampled as a unique block to preserve the correct interaction between the specific power amp and the speakers. Our 64-bit (double precision) NLC engine allows up to 40 kernels (harmonics). In addition, a complete set of parameters gives the full control over the power amp headroom, the type of clipping and the interaction of the negative feedback with the Depth and Presence knobs.
 
The proprietary solutions just described are grouped under a common acronym: DNC+ (Double-Precision Non-Linear Computing and Convolution).

Shaper

The input signal can be processed by activating a shaper before the preamp. This block allows to select one of the following:

  • a Low Cut
  • a Mid Boost
  • a Graphic Equalizer
  • a Parametric Equalizer
  • a Compressor
  • an Overdrive circuit
  • a Distortion circuit

 

Wah, Overdrive & Distortion — Fully Tweakable!

All DiBiQuadro amp simulations include the following effects, fully tweakable at component level:

  • A beautifully voiced Wah effect. The frequency parameter can also be automated via your DAW.
  • An Overdrive with two modes: TS (symmetric clipping) and SD (asymmetric clipping).
  • A Distortion with three modes: MDP (Distortion+ style), and 250/308 (Classic Preamp) modes.

Both Overdrive and Distortion allow to select the type of diode:

  • Silicon
  • Germanium

The diode characteristic and topology (only positive, only negative, one against one) can also be modified.

 

Automations

Every knob, button and state of the Preamp and PwrCab sections can be automated in your DAW. This provides a new level of integration of DiBiQuadro plugins with the time-based events of your project.

Audio Samples

We pour our passion into achieving the perfect representation of the hardware. Don’t just take our word for it—let your ears be the judge.

The Renderer

The Renderer is a stand-alone application to process an input wave file in OffLine mode. It can be invoked via command line too. Its purpose is to render long and processing demanding configurations (e.g. high upsampling).
