The 6020 Ultimate EQ is a collection of ten equalizer models using the popular module format leveraging McDSP’s 15+ years of design experience.

All 6020 Ultimate EQ modules are designed by McDSP, drawing on inspiration from classic and modern equalizers over the last four decades. Each module is easy to operate, and yet has enough sophistication for the most discerning professional.
Whatever your style, from smooth tube emulations to aggressive solid-state designs, the 6020 Ultimate EQ has a custom-made equalizer module that is just right for you.


  • 10 EQ modules in a single interface

  • Input & output control

  • Analog Saturation modeling

  • Double precision processing

  • Ultra low latency

  • Mono and stereo versions


  • The McDSP E670 module has three bands, each with its own continuous gain and frequency controls. The E670, like the original 664 module, is a program equalizer – a gentle set of EQ curves to tweak the tonality of the input signal.

  • The Moo Q module is a program equalizer like the E670, but derived from all tube designs of the last few decades. Three bands with continuous gain and frequency controls are included, plus some ‘tube accents’ in the output stage of the equalizer.

  • The iQ has only two bands – a low shelf EQ and a high shelf EQ. Additional circuitry is included for coloring the sound, even when the all equalizer gains are set to zero. If you are looking for some low end ‘glow’ or high end ‘sheen’, the iQ module is a good choice.

  • The E300 and E301 modules have the same frequency ranges, with the E301 narrower in bandwidth. Both modules are fairly utilitarian – good for shaping up guitar track tones, bringing out a vocal, or getting the most out of your drum tracks.

  • The classic high pass filter, low shelf, parametric, and high shelf combination makes the British-E module useful for many mixing applications.

  • Using the same filter and equalizer configuration as found in the British-E module – a high pass filter to carve out the rumble, capable low and high shelving EQ, and a fairly flexible parametric EQ, the EZ Q module gets the job done.

  • The EQ’76 module is meant to be paired with the SST’76 compression module from the 6030 Ultimate Compressor. The EQ’76 has four bands of parametric equalization, each with a slight Q-gain dependency.

  • The FRG EEE is a capable equalizer – with the low and high shelving bands performing some amount of cut/boost to offset the boost/cut selected – a clever design technique from many classic equalizers.

  • The E357 module is three bands of aggressive equalization. The shelving bands have more punch at the low end, and a brighter top end, than any other shelving EQ in the 6020 collection.
