Mars800 is a faithful software 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, the 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.

Mars800 doesn’t stop at its core sound: two popular mods, called 34 and 36, take its tone even further.

Mod 34: This modification was created at the request of a player seeking more distortion without adding another gain stage. The modification pushes the Mars800 into higher-gain territory, giving it a smooth, compressed tone with more sustain. It tightens the low end and adds extra saturation, perfect for players wanting a boosted rock sound with added bite. This mod was famously used on Use Your Illusion by Guns N’ Roses, providing the thick, powerful crunch that’s both smooth and aggressive. Its ability to compress and sustain made it ideal for the riffs and solos that defined 80s and early 90s rock.

Mod 36: This mod is a refined version of the legendary Mod 39, which evolved from an earlier 1959T amp modification. The original version featured an added gain stage using the tremolo valve, but later iterations simplified the design to make it more streamlined and widely used. Building on this, the Mod 36 was developed to deliver even more gain and depth. This mod was used on Appetite for Destruction and delivers a thicker, more aggressive tone with boosted bass response, making it perfect for players craving a heavier, modern sound while retaining a vintage edge. The Mod 36 is known for its saturated tone, making it a favorite in hard rock and metal.

These mods expand Mars800’s versatility, making it suited for anything from classic rock crunch to high-gain, saturated lead tones.

But that’s not all. The Mod 34 and Mod 36 include three exclusive, recallable circuit presets: Classic, Modern, and Extreme. Each preset is crafted to deliver a unique tonal character, making it easy to shape your sound and refine your creative vision.
