The Unholy pedal was the first physical pedal designed by our Lead developer Ryan (in the Revolt Custom Audio era). It’s a unique fuzz/distortion hybrid circuit, the positive waves are soft clipped and the negative waves are hard-clipped like a fuzz distortion would be.

This is a wide ranged distortion that can be used for more than just guitars. Try it blended on your vocal and drum busses for grit and character

The unholy was also the first distortion algorithm wrote specifically for Revolt DSP, this very pedal is special to us, it shows our history and even the origins of our first colour scheme

For that reason, we’ve brought it back for free with our latest generation graphics.

Who knows, we may even do some limited runs of the physical pedals again one day…

One distortion plug-in to rule them all. Black Diamond Distortion is the first plugin from Aspen Instruments. It is a flexible distortion engine designed to cover everything from subtle preamp-style warmth to aggressive modern waveshaping. You can start from a curated library of presets—including classic hardware-inspired designs—or build your own distortion from first principles using four distinct editing modes.

Harmonic Mode is the “bunny hill” of the plugin: it makes it extremely easy to dial in great-sounding distortion quickly. Nearly any configuration of the harmonic sliders produces a usable, musical result.
Under the hood, this mode gives you direct control over which harmonics are excited by the distortion algorithm. Traditional harmonic distortion plugins—often based on Chebyshev polynomials—tend to generate spiky waveforms that are difficult to manage in mixing and mastering. Black Diamond improves on this approach with a novel algorithm that excites harmonics while maintaining a significantly higher crest factor (the ratio between peak headroom usage and RMS energy). The result is distortion that is both harmonically rich and mix-friendly.

Spline Mode allows you to shape the transfer curve using spline anchors. You manipulate the curve directly by dragging these anchors in the editor.
The spline-fitting algorithm is optimized to use as few anchors as possible, which makes each anchor extremely powerful. A single adjustment can reshape large portions of the waveform, encouraging broad, intentional changes rather than tedious micro-editing.

Brush Mode is designed for adding texture and irregularity to the distortion.
The standard brush lets you draw the distortion curve pixel by pixel. Because humans are not particularly good at drawing smooth curves, this often results in “broken” shapes—and sometimes that brokenness is exactly the sound you want.

To compensate for this limitation, the Roller Brush smooths the curve as you draw, flattening jagged edges that can otherwise lead to overly brittle or unstable distortion.

In addition, several texture brushes introduce controlled noise into the curve. These brushes create subtle randomness and unpredictability, making this mode especially fun and rewarding to experiment with.

Equation Mode is the core of Black Diamond. It allows you to define the distortion directly by entering the mathematical equation that computes it.
For users willing to learn a small amount of signal processing, this becomes an extremely powerful tool. Math describes nonlinear behavior far more precisely than manual curve drawing ever could. In fact, equations are the foundation of Harmonic Mode—Equation Mode simply removes the guardrails. This opens the door to experimenting with an effectively infinite range of distortion algorithms.

After 8 months of hard work, they are finally here: LS1176 BLK & BLUY

Punchy, fast attack, massive sound, and true transistor saturation : right inside your DAW. Whether you’re mixing vocals, guitars, synths, kicks, snares, or drums, you’ll need this plugin at some point. It’s not just a recommendation… it’s a necessity

LS1176 BLK – the classic black FET compressor, completely free for everyone. Inspired by legendary analog units: punchy, colorful, and perfect for adding character to your mix.

👉 LS1176 BLUY – the advanced version, even more versatile, with massive and detailed saturation. Available free for 1 month for everyone 🎁, then exclusively via the store or through a Patreon subscription.

Why this economic model, and why support my plugins?

I’ve been creating plugins since 2022 now, with one clear goal: to provide high-quality free tools for everyone. When I was younger, I had no money to buy plugins, and I still remember the excitement of getting some of my favorite tools for free.

But making plugins costs money: licenses, software, graphics, interfaces, and more.
So, by purchasing a plugin or subscribing on Patreon (even just for one month), you help me continue the LOTUS SOUND AUDIO journey.
