Product Description

QB Emulates Legendary API 550B Vintage American Console Equalizer

QB, which is an API 550B analog modeling, is unbelievably fast because it is a pure DSP algorithm. You get renowned high-quality sound with the right curves. Put QB on a track, turn the high band all the way up, and hear the quality!

It has a modern, easy-to-use user interface. You’ll love its aggressive structure and proportional Q feature.

QB vintage American console 4-band parametric equalizer plug-in supports VST, VST3, AU, and AAX plugin formats.
