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.

My favorite EQ right now

Buttery smooth, it allows me to radically sculpt tracks without sounding unnatural. Excellent value for the price.

Oh it’s true, it’s true.

Wish I had discovered this gem a long time ago. Makes everything you put it on shine: vocals, drums, masters etc. Very intuitive. For me, it is sometimes that final step between a very good mix and a great one. I use it as a car stereo, tweaking those final settings to get things over the top. Kazrog has done it again. My only suggestion would be to add some sort of visual display ala the Pulsar stuff, so one can make even more informed decisions, and make the True 252 truly the go to mastering eq.

More Air Less Sibilance

I matched the frequency response curves with a handful of other top notch EQs and thought that the True 252 produces a sound that is slightly more airy and with less sibilance. Very nice emulation.

Having the volume matched with every move is the genius of this plugin.
So every alteration is clearly and truly heard and it sounds great.
