We've just released a collection of plugins that combine classic effects and Summing Tube Amplifier (STA) which mixes the wet and dry signals as well as it adds a nonlinear distortion resulting in more vintage sound.
Collection contains Chorus, Flanger, Phaser, Enhancer and Preamp.
Some of the plug-ins were published before as single items (USD 19 each), but now they are joined in a bundle of five effects (USD 49). In version 1.5 plugins gained improved CPU efficiency, better sound and new GUI.
STA Plugins run on PC and Mac in VST2.4, VST3, AU and AAX formats.
