Overloud releases EQ550 Gem - gives away 1000 free licenses each day for 1 week


Overloud has released EQ550 and is giving away 1000 free licenses each day, for the first week.

EQ550 is the simulation of the most renowned American Proportional EQ, based on custom op-amps. All the components of the original circuit have been modelled, including the rich harmonics and saturations that naturally occur when the equalizer is operating.

EQ550 is the latest product in Overloud's Gems plugin line dedicated to mixing and mastering.


  • Realistic simulation of the original Proportional Q equalizer.
  • 5 bands eq: 2 shelving/peaking, 2 peaking, 1 high cut, 1 bandpass.
  • Individual band Cue.
  • Continuous frequency selection.
  • Simulation of all transformers in the original unit.
  • Low CPU usage: more than 1500 instances on a Macbook Pro Retina.
  • Multilevel undo-redo.
  • A/B Comparison.
  • Lots of presets designed in real mixing sessions.

EQ550 extends the features of the original hardware and joins the flexibility of the digital world to the character of the analog processing:

  • Band Cue: the Cue button allows to hear the part of the frequency spectrum that is being affected by that band.
  • Continuous Frequency Selection: while the original hardware has preset frequencies only, the EQ550 allows to select all the intermediate frequencies.
  • Additional Mid Band: while the original hardware has one Mid band only, we added a second band for increased flexibility.

EQ550 introductory offer

EQ550 is available as VST, AudioUnit and AAX plug-ins as well as stand-alone application, 32 and 64-bit for macOS and Windows operating systems.

EQ550 will be launched at no cost for 1 week only, from March 12th through March 18th 2018. The list price will be €139 / $139 after March 18th.

I couldn't get this yesterday, because they had already reached their 1,000 license limit for that day. I tried again this morning, and managed to get it downloaded and licensed before they hit their limit again today. With over 1,000 downloads per day, it seems like a popular plugin so far. I only had a few minutes to actually try it out today, but I think I'll really like it. If you want it, be sure get it soon, and don't give up if you aren't lucky enough to get a free license on the first attempt. Just keep trying, till you get lucky. :)
