PSP MasterQ is a high quality parametric equalizer designed to operate at sampling rates ranging from 44.1 to 192kHz .The plug-in (VST and RTAS for Windows; AudioUnit, VST, RTAS for Mac OS X UniversalBinary) contains seven filters: 12 or 24 dB/oct low cut and high cut filters, low shelf and high shelf filters, and low mid, middle and high mid peaking filtersall of them with adjustable frequency and Q factor over a wide range. The plug-in also includes a high precision EQ graph to display an overview of the EQ curve, as well as display the individual characteristics of each filter.

I was most impressed by Master Q, for both its sound and PSP's trademark versatility. Although EQ preferences are a matter of taste, I found Master Q to sound very good, with extremely flexible curves, and it's far more versatile than the competition.
Martin Walker, Sound on Sound magazine

ComputerMusic award PSP MasterQ sounds great on most things, but it is especially good for anything with a lot of harmonic content - such as vocals, guitar or even entire mixes.
Computer Music magazine

In short, I have no reservations about saying the MasterQ is truly mastering-grade. [...] This is one heck of a great plug-in, and at this price point, I dare say the best value on the market.
