PTEq-X is a digital emulation of 3 famous vintage passive program equalizers.

It has been developed to have all the characteristics of the original hardware, plus some circuit improvements and additional features to increase its versatility.
Every single component on the signal path of the real analog circuit has been taken into account and modeled in the best possible way to match the original sound, keeping an eye on CPU performance and real-time playability at the same time.
PTEq-X is meant to be used as a studio equalizer for tracking, mixing and mastering inside hosts capable of VST or AU Plug-Ins support.

Main Features:

  • Three different equalization modules with perfectly analog curve response even at highest frequencies.
  • Ignite Amps 3rd generation triode stage analog modeling for 4 different tube types.
  • Additional selectable frequencies for the PEQ1A model, compared to the original design.
  • Refined filters frequency precision for the MQ5 and HL3C models, compared to the original design.
  • Switchable equalizers and tube stage modeling for better CPU usage management.
  • Switchable linear phase oversampling for aliasing reduction.
  • Global input / output level controls.
  • Mono / Stereo processing support.
  • Double precision (64-bit) floating point processing.
  • Fully automatable controls.
  • Ignite Amps proprietary preset management system with bank file import/export functions.

A great EQ for broad, non-surgical applications. I find PTEq-X to be a useful tool in mixing guitars and for vocal treatments, as well as a handy addition to my mastering chain. If you're looking for an EQ that allows you to cut or boost exact frequencies, you may want to look elsewhere. But, for adding growl to your heavy guitars, or removing nasally frequencies from a vocal performance, PTEq-X is your go-to.

Love it! It's a really fantastic piece of software except for randomly muting some tracks. Disabling/enabling solves that until it randomly mutes the track again. As this happened on a kick track first I assumed it was a peaking problem but no - completely random and not reproducable. Can work for hours and suddenly the kick is missing from the track..so I've got to switch off/on. But I wouldn't bother doing this if it wouldn't sound so amazing.

It's a great plugin. But needs some bug fixes.

The site still says hacked btw.

Back to the plugin, when i use this in ableton and reopen a project, some sounds are completely panned to the right or i get a huge amount of destortion. By swinging of the tube or fiddle around with the bandwidth knob fixes it. But when u have running several instances of this plugin its a mess to see which one of this plugin causes the problem.

Will there be a update of this one? It's by far the best pultec i ran into (free that is)

Can you please answer developer?
