QB3 is a vintage-style 3-band EQ plugin designed to add character and flexibility to your audio. Each band allows adjustment of the center frequency and gain, with additional control over the slope for low and high shelving bands and bandwidth for the mid peaking band. This range of controls enables a wide variety of tonal shaping, from sharp cuts to smooth boosts, making it suitable for enhancing different elements of your mix.

Unlike clean and transparent equalizers, QB3 introduces a subtle blend of harmonics, saturation, and low-level noise that adds warmth and depth to your sound. It provides a distinct sonic signature that enriches tracks with an organic feel. Additional features include an optional 40Hz cut to optimize low-frequency headroom and a built-in limiter to tame peaks, ensuring your audio remains polished and controlled throughout the mixing process.

QB3 offers full stereo processing and precise control with non-linear knobs that allow fine adjustments, along with a master gain control for overall level management. The plugin comes with 33 presets to help quickly dial in a variety of tonal settings. Its unique combination of classic EQ functionality with subtle coloration makes it a powerful tool for producers and engineers seeking both tonal shaping and sonic enhancement.
