True 252 - Vintage Graphic EQ

Following in the line of vintage analog emulations from Kazrog and Powers Music Group, such as True Iron and True Dynamics (both of which received NAMM TEC Award nominations), True 252 is an emulation of the highly sought after Langevin EQ 252A Graphic Equalizer.

In building this emulation, copious measurements were made of the original hardware in the Powers collection, and every effort has been made to accurately represent it in the digital domain - including the extremely musical EQ curves that inspired the original Motown-style EQ circuit, and gentle natural saturation of the original unit.

This equalizer is incredibly intuitive, and brings life to masters, buses, and individual tracks in a way that feels effortless and immediate.

Demo limitations: 

  • Random silent output
  • Preset save disabled

Kazrog plugin demos are time-unlimited, but have the above limitations. Purchasing the plugin removes these restrictions. 


  • Highly accurate emulation of the Langevin 252-A Graphic Equalizer
  • Gain compensation - maintains the same apparent loudness irrespective of the EQ slider settings.
  • Continuous gain control - not stepped as with competing plugin emulations of similar EQs.
  • "Cramping-free" equalization. (More info about EQ cramping, and why it's bad, in this video from Dan Worrall.)
  • Standard Kazrog preset manager with A/B compare.
  • Compensated internal bypass.
  • Separate oversampling settings for realtime and offline processing, adjustable on the fly.
  • Two UI themes - black and gray - based on the faceplates of the original 252-A and its cosmetic variation, the 270.

True 252

Its time to go for natural and VERY musical track / production cohesion. Time to give the parametrics a little break and see UNITY what True 252 can achieve.
Me I love it.

my first auto gain compensated eq

this is my first auto gain compensated eq. never knew I need age in an eq. I do now though. I really like this plug-in. never harsh... and super easy and quick to use. I also love the restriction. no endless fiddling. very impressive work. this is certainly my favorite eq.

Perfect amount of color

Best in-the-box EQ I've ever used. The preset menu is well done, auto-gain is incredibly convenient, and it sounds awesome on a bus or a master too.

Sweet Equalizer

Very good sounding EQ, works good on anything you put it on, nice EQ to have in the toolbox, I'm very happy with it.

Creamy Retro Sparkle

As usual for Karzog, subtlety is the game. This plugin adds a kind of creamy retro sparkle that you swear you must be imagining, but when you turn the darn thing off, you notice! I'm now over using it, but I can't stop! Awesome plugin!
