Mars800Free (Full)

Mars800Free is a faithful simulation of one of the most iconic amp heads in rock history, capturing the essence of a powerful, single-channel amp with raw, unfiltered tone. Designed with EL34 power tubes, it offers the unmistakable bright, gritty, and punchy sound that defined countless classic rock and metal tracks.

With controls for Gain, Bass, Mid, Treble, Presence, and Master Volume, Mars800 responds well to adjustments, delivering anything from a thick crunch to a searing lead tone. While it’s simple in layout, this amp simulation is powerful in sound, achieving a natural, organic distortion that’s clear and dynamic. Loud and unapologetically bold, Mars800 is the perfect choice for players who crave an authentic rock sound with vintage grit and modern reliability.

Non-Plus-Ultra Preamp

Non-Plus-Ultra Preamp represents the perfect approach to circuit modeling. Mars800Free 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!

Pwr/Cabs: Non-Linear Convolution

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 allows the full control over the power amp headroom, the type of clipping and the interaction of the negative feedback with the Presence knobs.



The proprietary solutions just described are grouped under a common acronym: DNC+ (Double-Precision Non-Linear Computing and Convolution).

Mars800Free is delivered with 4 Pwr/Cabs.

Shaper

The input signal can be processed by activating a shaper before the preamp. This block allows to select one of the following:Low Cut
Mid Boost
Graphic Equalizer
Parametric Equalizer
Compressor
Overdrive
Distortion

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.

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).
