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.

      The best spring reverb in a plug-in

      This recreation of the original sounds incredible. Picked it up on sale with the EMT plate. My reverb game has leveled up big time.

      Nice subtle spring

      Quite a subtle, hi fi spring, sits in the mix really nicely. Only downside is that I'd prefer a bit more variation in sound between tank A and B, but regardless it sounds great

      Lovely Springverb

      I love it but use it not often. Would choose it more if the decay time would be a load shorter. Please. It works with a gate behind the verb, but hey.

      Unique

      Unique, useful in specific situations, but far from versatile.

      Ooooooh Yeah!

      I've never worked with the original so I can't compare the two, but this reverb sounds incredible. Period. I'm kind of a spring reverb fanatic, and have a custom setup with 4 reverb tanks in addition to those built-in to my amps and cabinets.

      The AKG BX20 plugin doesn't really sound like *any* of my spring reverbs. While it can't reproduce some of the low-fi trashy and "sproingy" sounds I love about my hardware 'verbs, the BX20 DOES offer an incredibly smooth, deep + wide sound that augments but doesn't mask the source (unless you want it to). It sounds closer to a plate in my opinion, and arguably even better than the beloved UAD EMT 140

      Overnight, the AKG BX20 has joined the Lexicon 480L as my absolute favorite UAD reverb plugins. I can't imagine you'd be disappointed.

      Sounds great

      This is a fantastic spring reverb ... I use it on vocals and guitars and it brings beautiful "air" to my productions ...

      Lush and Liquid

      Liquid Gold. I am extremely happy I purchased this even though I had the UA Lexicon reverb. I admittedly thought "Spring" Reverb was a reference to the season a few years back. Now with a basic understanding of how Spring Reverb works it makes sense that the powerful emulation of such a classic piece of gear was only given a green light to UA. Used on an auxiliary track I have no issues with the upsampled latency and can substitute processed rooms and reverbs in my Roland TD-50 with the Ocean Way Plug-in and the BX 20 to transform the module into an entirely new beast, with the most organic and high end ambience available. Makes an enormous difference.

      Interessante...

      Interessante, ma mi aspettavo di meglio dopo il trailer.
      Fa il suo sporco lavoro sulle chitarre per riprodurre quei riverberi classici di quell'epoca, ma non mi ha entusiasmato la regolazione del decay che sui Synth può risultare fastidioso.
      Attendiamo un aggiornamento!

      famelico ma stupendo

      Ho subito messo al lavoro questo plug-in come riverbero di riferimento e mi sono subito ritrovato nelle mie antiche timbriche ricche e piene di profondità. Ottimo lavoro
