DiBiQuadro Audio have released Mars800Free, available as a FREE download.
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 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!
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.
Mars800Free is available to PC and Mac users (VST3, AU and AAX).
