Spring captures the unique sound and character of classic artificial reverbs found in guitar amplifiers, offering an authentic spring reverb experience. Beyond emulating traditional spring tanks, it provides physical parameter controls that extend creative possibilities, allowing users to customize their sound in ways not possible with hardware alone.

Users can shape their tone by adjusting core parameters such as Tension and Number of Springs, which influence the springiness of the reverb effect. Additional controls for Resonance, and Low and High damping enable precise tailoring of the reverb texture. The plugin also incorporates performance features like the Ribbon controller for smooth transitions between settings and a programmable HotSwitch for instant sound changes, enhancing live performance and sound design flexibility.

Spring includes a tube amp-style tremolo effect that can be placed before or after the reverb, adding depth and movement to the sound. It supports tempo-synced decay and modulation options to create chorus-like effects and other unique textures. Compatible with Mac, Windows, and iOS platforms, it offers various plugin formats and standalone operation, making it a comprehensive tool for guitarists and producers seeking both classic and experimental reverberation.
