Post Description

PSP sQuad is a bundle of FIVE high-quality equalizer plug-ins (VST and
     RTAS for Windows x32 or x64; AudioUnit, RTAS and VST for Mac OSX
     universal binary). PSP sQuad equalizers are inspired by the best
     features and characteristics of classic analog hardware-musicality and
     simplicity. Although these EQs are easy to use we expanded their
     functionality by several features including variable high pass filters
     or switchable steepness for the shelving filters.These EQs are CPU
     efficient enough to be used at every stage of the creative process,
     from composition to tracking to final production/mixing/mastering. 

     The five processors of PSP sQuad are: PSP ClassicQ, PSP ClassicQex,
     PSP ConsoleQ, PSP preQursor and PSP RetroQ.
