Loved and coveted by sound engineers all over the world for its super huge bass and its silky shiny treble, the PE 1C is Tube-Techs clone of the famous Pultec tube-driven passive equalizer. It does things no other equalizer can, and when you start twisting the knobs you will find it's more versatile than it may appear at first.

We think the sound from this equalizer is the reason why some people started spelling "fat" with "ph" when describing a sound. The PE 1C will give you the most thunderous and solid low end on the planet, and in addition to that, a treble that is so silky and sweet you just want to cuddle into it.

The Tube-Tech PE 1C is a passive, tube-based equalizer suitable for many different sources ranging from bass drums and guitars to vocals, and not least for giving full mixes that extra weight and shimmer. The equalizer features a Low Frequency section made up of two low shelf filters which can be combined to attenuate and boost at the same time. These filters are actually bit apart in frequency even if they are controlled by the same frequency selector, and if you find the Boost gives you too tubby a sound, the Attenuate knob will clear that up for you.

The High Frequency section has a peak and shelving filter working in parallel, which provides a smooth and bright top end while never becoming brittle or harsh.

The Tube-Tech PE 1C plug-in by Softube captures every nuance of the hardware version. It has an extremely analog sound which is evident as soon as you start using it. Every aspect of this studio standard, 25 years in the making, is now finally available as a plug-in.

In Short

  • The Pultec style equalizer!
  • Classic Tube-Tech sound, created together with the designers at Tube-Tech.
  • Each and every component carefully modeled.
  • Unique interaction between filters.
  • Modeled output transformer.
  • Extremely analog behavior of frequencies, phase, distortion, etc.
  • CPU friendly.

We are excited to experience the PE 1C in the digital domain and impressed once again by the skills of Softube.

John G. Petersen, Designer and president of Tube-Tech

Silky smooth tones. Easy to use. Works in many mix situations. A useful addition to your mixing toolbox.

It's just like the hardware. Really good. It sounds really smooth and musical.

Rob Chiarelli, Mix Engineer for Leann Rimes, Aaliyah, Ray Charles, Will Smith, Christina Aguilera, etc.

It's a unique processor for bottom and top end treatments and its sound is so warm that sprinkling a little PE 1C onto vocal parts or using it more comprehensively on bottom-heavy content will allow you to produce results unattainable with regular EQs.

The PE 1C EQ is on every kick drum, it's on vocals, it's all over the place.

Greg Wells, Producer and songwriter for Katy Perry, Weezer, Adele, Timbaland, Mika, OneRepublic, Pink, The Deftones, Rufus Wainwright, etc.

The Tube Tech EQ is my go-to bass eq. Best thing ever on bass. Boost a little 60 and 1.5k and there ya go! Dialed!
