An algorithmic spring reverb
HoRNet Plugins is proud to announce the release of SpringVerb, a new algorithmic spring reverb plugin based on physical modeling. This plugin brings the unmistakable character of classic spring reverbs—as found in vintage guitar amplifiers and analog studio gear—into the digital domain with an extraordinary level of customization and sonic detail.
Unlike traditional algorithmic reverbs that simulate reverberation with basic delay lines and filters, SpringVerb uses physically modeled springs, allowing for the recreation of the mechanical behavior of actual spring tanks. This approach gives users not just the sound of vintage hardware, but also direct control over the physical properties of the virtual springs themselves, enabling the creation of both faithful emulations and new, experimental textures.
Spring reverbs first appeared in the 1930s, developed alongside plate reverb as one of the earliest methods for generating artificial ambience. Thanks to their compact design and distinctive tone, they quickly found favor in Hammond organs and eventually became standard in guitar amplifiers throughout the 1950s and 60s. Since then, the spring reverb has become an iconic effect, contributing to the signature sounds of countless rock, surf, psychedelic, and reggae recordings.
In creating SpringVerb, HoRNet didn’t just aim to replicate a sound—we sought to rebuild the mechanics behind it. By combining published acoustic research with our own innovative DSP techniques, we’ve built a reverb that responds and resonates like a real spring.
One of the most powerful aspects of SpringVerb is the ability to manipulate the intrinsic parameters of the modeled springs. Users can change:
Vibration Time: This defines how long the spring vibrates after being excited, effectively controlling the reverb length. Whether you want a quick slapback or a cavernous tail, SpringVerb can deliver.
Damping: This affects the decay speed of the spring. Lower damping values produce longer, more resonant tails, while higher values yield tighter, more controlled reflections.
Resonance: Controls the self-resonant frequency of the spring, shaping the core tonal color of the reverb.
Brightness: Alters the highest frequencies the spring can reproduce. This influences not just the tonal shimmer but also the perceived clarity of the reverb.
Together, these controls let users go beyond presets and standard algorithms. You can sculpt reverb from the ground up, whether you’re aiming for an exact replication of a Fender spring tank or designing something entirely new and unique.
Although SpringVerb is grounded in physical modeling, we’ve added several features to make it more versatile in contemporary production workflows.
Dry/Wet Mix: Allows seamless blending of the reverb signal with the dry input, enabling subtle enhancement or full immersion.
Diffusion Control: While not an inherent characteristic of physical springs, this parameter introduces a more complex reverb texture by dispersing reflections. Lower values produce a crisp, metallic bounce typical of analog tanks. Higher values simulate the smoother decay of digital reverbs, creating lush soundscapes without sacrificing the core character of the spring.
SpringVerb lets you choose the number of simulated springs, each affecting the spatial characteristics of the effect:
One Spring: Produces a classic mono spring reverb with a tight, bouncy response. Ideal for vintage guitar tones or raw, old-school textures.
Two Springs: Creates a stereo image, widening the reverb field and introducing subtle interaction between the left and right channels for a more immersive experience.
Three Springs: Offers the richest sound with deep modulation and shimmer, making it perfect for ambient work, cinematic transitions, and modern experimental sound design.
Each configuration opens up different spatial and tonal possibilities, making SpringVerb adaptable across genres—from blues and rock to synth-heavy electronic compositions.
In keeping with HoRNet’s mission to make professional tools affordable, SpringVerb is available now for just 12.99€. At this price point, producers at all levels—from bedroom creators to studio professionals—can gain access to a powerful, authentic spring reverb that rivals hardware costing many times more.
There are no hidden upgrade costs or tiered versions—SpringVerb is fully featured and ready to deliver outstanding results out of the box. Whether you’re adding subtle space to vocals or drowning synths in analog reverb bliss, SpringVerb has you covered.
HoRNet SpringVerb redefines what spring reverb can be in the digital age. By combining physical modeling, parameter depth, and creative flexibility, it offers an unmatched tool for sound design and musical production. It’s not just about emulating the past—it’s about taking a vintage idea and pushing it forward.
With control over every core element of the spring’s behavior, integrated modern tools like diffusion and mix balance, and multiple spring configurations, SpringVerb provides everything you need to bring character, space, and motion into your mixes.
