Relab Development Q82 Natural Resonance Reverb - ESD

Relab Development Q82 Natural Resonance Reverb is a dual-engine plug-in recreation of a sought-after early 80s hardware reverb, famed for its uncannily realistic room ambience and luxurious long tails. Using advanced machine learning and meticulous modelling, Q82 captures not only the sound but the feel and quirks of the original unit, giving you a premium, hardware-like reverb experience entirely in the box.

At its core, Q82 combines two independent reverb engines, each with four outputs, so you can sculpt width, depth and placement in the stereo field with a level of control that typical reverbs simply cannot match. Add in hand-tuned 8-voice modulation, flexible bandwidth shaping and the ability to switch between pristine German and characterful US algorithms, and you have a powerful ambience tool that can move effortlessly from subtle natural spaces to huge, cinematic soundscapes.

Whether you are mixing modern pop, film scores or atmospheric guitar soundtracks, Q82 makes it easy to dial in reverbs that sit perfectly in the mix. The carefully designed controls feel musical and intuitive, letting you focus on the emotion and space of the track rather than wrestling with complex routing or menus. You get the sonic character of a rare, expensive studio classic, without the cost, maintenance or footprint of the original hardware.

Because Q82 models the behaviour of the original circuitry in depth, including clock instability and component ageing, it responds dynamically as you work, evolving from crisp, fresh tones to warm, lived-in ambience. This gives your mixes a distinctive, three-dimensional signature that helps vocals, drums, synths and guitars feel more alive, engaging and professional.

Dual-Engine Reverb Control

Q82’s twin reverb engines, each with four outputs, let you fine-tune stereo width and front-to-back depth in real time. You can blend the two engines to create complex, layered spaces that sit exactly where you want them in the mix, from tight, intimate rooms to expansive, enveloping halls.

Vintage Algorithms with Temperature Control

Switch between two distinct reverb algorithms: a clean, factory-spec German model and a more coloured, time-worn US version. The Temperature Control knob lets you emulate the sound of the hardware from cold start-up to the rich, warm tone of a unit that has been powered for days, so you can choose the exact era and character that suits your track.

Hand-Tuned 8-Voice Modulation

Relab’s Advanced Chorus Ensemble (ACE) modulation is deeply integrated into the reverb algorithm, using eight individually hand-tuned voices. This adds natural movement, depth and complexity to the tails, making the space feel organic and alive rather than like an effect sitting on top of your sound.

Expanded Bandwidth and Natural Resonance

Q82 extends the original hardware’s bandwidth with a unique, resonant frequency response that can be set from 4 kHz to 16 kHz. Instead of a simple low-pass filter, the internal behaviour of the sample rate and analogue-style filters has been recalculated using carefully chosen roll-off points, giving you a more musical, natural-sounding ambience that flatters a wide range of sources.

• Authentic 80s Hardware Reverb Recreation - Q82 2.0 uses advanced machine learning to capture the nuances, non-linearities and quirks of a legendary early 80s resonance reverb. You get the highly realistic ambience and long reverb times of the original studio classic, helping your productions carry the same depth and character as high-end vintage rooms.
• Powerful Dual-Engine Architecture - Two independent reverb engines, each with four outputs, work together to give you precise control over stereo width and front-to-back placement. This dual approach lets you sculpt spaces that sit perfectly around your source, improving clarity and separation while still sounding lush and immersive.
• German and US Algorithms with Ageing Behaviour - Choose between a stable, restored German algorithm and a more unstable, character-rich US version that models an ageing crystal clock and components. The Temperature Control lets you move between cold and warmed-up states, so you can dial in anything from clean, modern reverb to vibey, vintage ambience.
• Hand-Tuned Modulation and Flexible Bandwidth - The integrated 8-voice ACE modulation is hand-tuned and embedded into the reverb itself, adding subtle motion and depth that feels like part of the room. Expanded bandwidth control from 4 kHz to 16 kHz with a specially designed resonant curve lets you tailor the top end to suit everything from dark, vintage spaces to bright, airy modern mixes.
