Three bands of EQ inspired by Rupert Neve’s most prized vintage designs. Class A gain blocks. Custom-wound inductors and transformers. The Rupert Neve Designs 551 brings the thick lows, powerful midrange and sweet highs of Rupert’s classic inductor EQs to the compact 500 Series format for the very first time.

So, what are inductors? They’re wires wound around a coil that provide a form of frequency-dependant resistance. When they saturate, they bring out beautifully musical harmonics that give your tracks the smooth, polished sound that has made Rupert’s consoles and equipment so desirable for over fifty years. This is an EQ with a truly vintage soul.

Great sounding eq 👍

By John Z on December 18, 2018

I've never been a huge fan of the EQ section on classic Neve modules like the 1073, 1066, 1084 but this more modernized design from Rupert is amazing. They smoothed out some of the nasty phase shift that could make the vintage Neve EQ's sound a little harsh. Super flexible and a great compliment to my API 550A's. Love them on drums especially.

This is a sweet sounding eq. It doesn't have the aggressive characteristics that some inductor eq's have. At first, it seems that the frequency choices are limited, but, with switchable shelving, narrow bandwidth switching in the midrange and the 80hz rolloff, you can do a lot. I own API, Avedis, Kush and Chandler hardware eq. While I like them all, I find myself wanting to go the 551 more as time goes on. I plan to buy another one when I can.
