The Kludge Audio 506 Equalizer features three bands of great sound, with tunable top and bottom shelf filters and a widely-sweepable midrange peaking filter. Not too wide. Not too narrow. It's just right.

The Kludge Audio 506 Equalizer is a standard inductor-based topology just like we were using in 1975, but it's built with materials and performance that were impossible back then.

Kludge Audio started with a classic inductor design and took it to the limit with custom built inductors and precision amplification that sound cleaner and more subtle than anything possible before. It's the best of old and new. It's an old design, built by hand with traditional methods and solid design, but built to be cleaner and more accurate without losing the characteristic sound of the inductor equalizer.

It's the inductor equalizer of the future!

Kludge Audio 506 Equalizer Features

  • It is a general tone-shaping equalizer, not surgical.
  • It was initially designed for classical music so it is super clean.
  • It has inductors but is quieter and cleaner than competing inductor equalizers.
  • You can make aggressive changes without the sound coming apart.
  • It can be set to well above the audible band for "air band" boost or to cut ultrasonic noise when recording at high sample rates.
  • It is hand-built in the USA, to last a lifetime.

What We Think

avatar

The Kludge Audio 506 Equalizer is one of those pieces that immediately pulls you out of the modern, screen-heavy mindset and puts you back in touch with the music. While using it in the studio, it genuinely felt like working on a large-format console again. The sound is smooth, musical, and inviting — the kind of EQ you don’t analyze so much as feel. When we first patched it in on guitars, we found ourselves closing our eyes, listening, and turning knobs purely by instinct. No overthinking, just reacting to what the track wanted. That’s something you don’t experience very often these days, and it’s exactly what makes the 506 special. It dials in quickly, the moves always feel right, and the results are immediately satisfying. There’s a sense of connection that happens when using it — like the gear is working with you instead of asking for permission. It’s the EQ section of a high-end console distilled into a compact 500-series module, and it absolutely earns its place in a serious studio. If you’re looking for an outboard EQ that’s inspiring, musical, and a joy to use, the Kludge Audio 506 is an easy recommendation.
