The Rupert Neve Designs 511 3-band EQ puts the sound and function of classic vintage Neve modules in your 500 Series frame. This dynamite EQ calls upon the Mr. Neve's most coveted designs from the 1970s with hand-wound inductors, custom transformers, and Class-A amplifier blocks for the most musical, three-dimensional tone shaping imaginable...so good, you'll always want it on the way in rather than waiting for mixdown.
