The only AKG-licensed emulation of this one-of-a-kind spring reverb.

Introduced in the late 1960s, the AKG BX 20 reverb was a high-water mark for AKG’s esteemed engineers. An ingenious assembly of mechanical and electronic componentry, the BX 20 offered the glorious depth and color of spring reverb without any of the limitations.

The AKG BX 20 Spring Reverb plug-in for UAD-2 hardware and Apollo interfaces is exclusively endorsed by AKG Acoustics, Austria and envelops your sources in gorgeously dark, dense ambience that only spring reverb can provide.

Now You Can:

Mix with the only licensed and endorsed AKG Acoustics BX 20 reverb plug-in

Envelop instruments in dark, dense, clear ambience with original dual spring tank configuration

Harness new "plug-in only" features like stereoized A/B Tank Select, Direct signal defeat, and BX 10 Tone controls

Mix with artist presets from Patrick Carney (The Black Keys), Vance Powell (Jack White), and Jacquire King (Kings of Leon)

Featuring the AKG BX 20 Spring Reverb.

Unparalleled Density

Unparalleled Density

The AKG BX 20's utterly unique character makes it a versatile tool for ambience as well as tone shaping. Its sonic personality features the quick onset of a classic plate reverb, and also the natural-sounding density and diffusion of a chamber — with little of the flutter or “boing” artifacts common with other spring reverbs. Unlike other spring reverb emulations, Universal Audio's hybrid delay network/convolution design provides the only plug-in representation of this mechanically controllable, acoustic ambience system. To that end, UA obsessively emulated a “golden unit” BX 20 from legendary producer, Jon Brion.

Spring Time

Spring Time

The BX 20 plug-in expertly captures the hardware’s unique two-stage decay. This yields warm, organic sounds whether it’s applied on percussion, vocals, or guitars, adding a unique timbre that can make individual tracks stand out — or melt away — in your mix. Short textures are chock full of colorful depth and dimension, while longer decays are rife with lush three-dimensionality, while never washing out.

New Features, More Control

New Features, More Control

The BX 20 plug-in provides the complete sound and features of the original, plus new "Mk II" features for an expanded sound palette. Tank Select provides the exact sound of the original A/B dual tank system, but includes a “stereoized” tank A or tank B, for more balanced stereo imaging. The Direct function allows you to mute the tank's direct signal for more control and minimizing conflict with the source audio — perfect for buses. The Baxandall-type tone controls — borrowed from the smaller AKG BX 10 — offers the last bit of seasoning to tailor your reverbs.

      My dear old spring reverb is back

      Je les ai toutes utilisé, de l'EMT à la STOKSTRONICS et même la BX5 pour commencer. Alors, quel bonheur de retrouver 40 ans plus tard ce son à l'origine de la matière analogique... Vive les reverbs à plaque....Et particulièrement cette BX 20 authentique.

      unique

      I bought AKG for my acoustic cello recordings.well, What can I say, you just put it on a recording and it sounds unique. AKG has a different sound from all reverb and it is a perfect match for cello.

      Amazing! Ignore the word 'spring' and listen to it, cause it's just great.

      Great reverb for a bunch of different sources and uses. Beautiful ambience and 'room' sound. Don't be fooled by the word 'spring' and assume it's only for guitar. This is definitely one of the greatest in-the-box reverb units. Well done, UA.

      Worth it

      I love the response and the ease you can edit. It does use a lot of processing power. Still worth it

      True vibe

      I`ve been using different real spring reverbs for years, they all have in common some nice density and “real vibe”. Uad BX 20 keeps that feeling to me, plus lots of flexibility. Couldn`t be happier with it!

      Beautiful dual-spring without the "sproing"

      Brilliant, lush, massiveness. Is that a word? It's a sound. Use it on everything.

      Dive In the Room

      Nice warm reverb. Organic room designing especially ducked by the kickdrum ;)
      But not usable for al purposes...

      This is a must if you want dark reverb that fills all the wholes in a mix!
