Summing Tube Amplifier (STA) mixes the wet and dry signals and it adds a nonlinear distortion resulting in a more vintage sound. Primarily, this effect is designed to be used as an insert effect to fully exploit the summing circuit. The plugin has also a "Wet only" option when only the signal processed by the tube circuit is sent to the output. It allows to use the plugin also in a send bus.
STA Preamp can give your mixes some extra value. Choose one of three types of tubes and control amount of saturation.
STA Chorus adds your instruments a little warmth and tickling vibe.
