The Rupert Neve 551 is the only 500-Series EQ designed by Rupert Neve himself, delivering the unmistakable vintage character of classic Neve consoles in a modern, compact format. Featuring three inductor-based EQ bands, custom transformers, and Class-A gain blocks, the 551 brings legendary warmth, punch, and sweetness to your 500-Series rack.

Why It Stands Out
Inspired by Rupert Neve’s vintage 1064 and 1073 designs, the 551 captures the creamy lows, musical mids, and sweet, airy highs of classic analog EQs—while offering greater flexibility and precision. Its proportional-Q midrange design makes it perfect for sweetening vocals, sculpting instruments, or removing problematic frequencies. The hybrid HF design blends vintage character with modern control, ensuring your tracks retain their warmth and presence without sacrificing detail.
