Teletone Audio has released Silver Spring ($79), a spring reverb plugin that captures the sound and behavior of 17 analog spring reverb units, available now for macOS and Windows in VST3, AU, and AAX formats.
While spring reverb is often associated with guitar amps and surf rock or dub music, I typically use it for adding a unique character to background vocals, leads, and various other elements in the mix.
Silver Spring brings this classic effect into exactly this type of modern production workflow.
The plugin samples a diverse range of real hardware units, grouped into five tonal families: Ripple, Silver, Splash, Springy, and Torrent. These families range from short, slapback-style reverbs to longer, modulated tails.
This variety of modes makes Silver Spring more versatile than you might expect from a spring reverb.
Each of the 17 reverbs was meticulously sampled using dynamic convolution, capturing how each unit responds to changes in amplitude and frequency over time.
This gives Silver Spring a more authentic feel than static impulse responses, especially when used on dynamic and expressive sources like vocals, synths, and live instruments.
The user interface feels familiar right from the start, since you get all the essential reverb controls like Mix, Decay, Pre-delay, and Drive.
The decay parameter is artifact-free, which sets it apart from typical IR-based reverbs that tend to glitch when changing tail length. The Drive knob applies tube-style saturation (odd harmonics only) to the wet signal, letting you add a bit of grit or glue to the reverb tail.
There’s also a high-pass and low-pass filter to control which frequencies get sent into the reverb. These filters are pre-reverb, making them convenient for carving out mud or high-end harshness before it hits the spring tank.
Teletone Audio included two additional switches to add more flavor. Enhance increases stereo width and scoops out some low mids, brightening the sound and making it more mix-ready. Modulation subtly animates the reverb tail by adding variation, giving it more of a lively and evolving feel.
My favorite thing about Silver Spring, though, is how easy it is to access a wide range of spring flavors with the Reverb Type selector.
Each model, ranging from Fender’s classic spring tanks and the Roland Space Echo to rarer units like the Hawk HR-12 or ADC MX-6, brings a distinct character. You can treat these like presets or tweak them further to create your own custom textures.
The preset browser includes settings tailored for specific instruments like guitars, drums, vocals, bass, piano, synths, strings, and buses. These presets make it easy to find a solid starting point for your instrument and then customize it if needed.
Despite the complex sampling behind the scenes, the plugin itself feels user-friendly and solid in terms of performance. The CPU load is surprisingly light, which means you can comfortably run multiple instances across your session without needing to set up return tracks.
Silver Spring is available now for $79. A fully functional 7-day free trial lets you evaluate it in your own projects. You’ll need macOS 10.11 or later or Windows 10, and the plugin runs in any DAW that supports VST3, AU, or AAX formats.
