AKG BX20 Reverb IR – Vintage Spring Depth with Modern Precision
The AKG BX20 is one of the most iconic spring reverbs ever made, and at Nevo Studios we have captured its unique sound with great precision through high-quality impulse responses (IRs). Built in the late 1960s and early 1970s, this reverb was designed by AKG to recreate the natural ambience of world-class concert halls. However, its spring design gave it a sound that became instantly recognizable — warm, deep, and full of life.
The Sound of a Classic
Unlike most spring reverbs, the BX20 delivers a big, dense, and complex tone with only a subtle hint of spring movement. As a result, it feels organic and natural rather than metallic or artificial. This makes it ideal for vocals, drums, and guitars where a smooth, cohesive space is needed. In addition, its open decay and wide stereo field help instruments sit perfectly in the mix without losing clarity.
Over the decades, the AKG BX20 has appeared on countless records. For example, artists such as White Stripes, Kings of Leon, and The Black Keys have used it to create rich, atmospheric depth. Even though it was built more than 50 years ago, the BX20 continues to inspire producers who want vintage warmth combined with analog authenticity.
Captured with Care at Nevo Studios
At Nevo Studios, the BX20 remains a key part of our analog reverb collection. We captured its sound through our Amek/Neve console and ATC monitoring system to preserve every detail. Therefore, the resulting impulse responses reflect the same depth and complexity that make the BX20 so special.
Each setting was recorded and refined to provide multiple tonal variations and decay lengths. Consequently, you can use these IRs for anything from short, tight vocal reverbs to long, cinematic ambiences. Moreover, the BX20’s natural tone blends seamlessly with both acoustic and electric instruments, giving your mix character without adding harshness.
A Timeless Reverb, Reimagined for Today
In short, the AKG BX20 Reverb IRs from Nevo Studios bring this legendary spring reverb into the modern digital world. They offer the same lush depth, organic warmth, and timeless character that made the original famous. Perfect for producers, mixers, and sound designers, these impulse responses add atmosphere, authenticity, and true analog depth to any production.
