From Overloud’s high-end GEM plug-in series, the EQ550 is modeled after a renowned American EQ created with custom op-amps. Overloud EQ550 has a Proportional-Q design, meaning that the bandwidth of the filters becomes narrow when the gain of the filter increases. For low-gain settings, the EQ delivers a smoother tone. Its character becomes more and more aggressive when the bands gain band is raised. This design makes the EQ550 unique.

EQ550 exactly reproduces the original frequency response even in the highest-end of the spectrum, near the Nyquist frequency, which is the point where most of the digital simulations fail. Thanks to 4th-gen DSP technology, Overloud has been able to achieve this result with no phase distortion and without using oversampling.

Beyond the Original Hardware

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 you 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, Overloud added a second band to the EQ550 for increased flexibility.
