PSP McQ emulates the distinctive sound and functionality of classic console equalizers, drawing inspiration from renowned MCI console EQs. It enhances these vintage qualities with modern features, including adjustable high pass and low pass filters, resonance control for shelving filters, and optional bell filters for the low and high frequency bands. Users can select from three nominal Q values for midrange filters, providing flexible tonal shaping options.

Designed for detailed track refinement, PSP McQ incorporates musical elements such as gain-dependent Q factors for midrange bell filters, allowing the filter bandwidth to dynamically respond to changes in boost or attenuation. This makes the plugin particularly effective for achieving precise tonal balance and improving track separation within a mix, supporting both subtle enhancements and more pronounced equalization.

In addition, PSP McQ features a second generation saturation option in its output section, which safeguards against digital clipping while adding pleasing harmonic distortion to signals pushed hard. This saturation effect operates after the output level control with a ceiling set just below digital full scale, delivering smooth overdrive that enhances the overall sound without compromising clarity or dynamic range.
