Description

Experience the Rupert Neve Designs 551 500 Series Inductor EQ Pair, where vintage meets modern in a compact yet powerful format. This EQ is a testament to Rupert Neve’s legendary audio engineering, bringing the iconic Neve sound to your 500 Series rack. With a design inspired by vintage classics, the 551 boasts custom-wound inductors, transformers, and Class A gain blocks, delivering that thick, resonant bass, and sweet, polished highs that define the golden age of analog.

Perfect for producers who appreciate both the classic tonal warmth and the precision of modern technology, the 551 EQ is not just a tool but a gateway to the timeless Neve sound, now accessible in the popular 500 Series format.
