WetChorus: Free Stereo Chorus and Vibrato by WET VST
Developer WET VST offers WetChorus, a free open-source stereo modulation plugin published under the MIT license. The effect models a bucket-brigade stereo chorus circuit derived from a classic 1970s guitar combo. Producers can download the binaries directly from the developer without registering an account.
Bucket-brigade processing
WetChorus reproduces the sonic character of hardware bucket-brigade delay lines, delivering classic chorus and vibrato textures. Instead of clean digital modulation, the plugin recreates the distinct stereo depth and subtle pitch movement associated with analog 1970s combo circuits. Because WetChorus is released as open-source software under the MIT license, creators can inspect, modify, and integrate the tool freely into their music production workflows.
