The latest desktop addition from Herbs and Stones is an analog multiband saturator and asymmetrical distortion device. 

Three Stems allows a signal to be split into three adjustable frequency bands which can then be sculpted with the saturation distortion circuit. 

Take distortion to the extreme when you pit frequency bands against each other, creating ring modulation and gating effects. High voltage inputs can bring unpredictable flavour to your drones or can be sculpted to a crisp finish, based on your tastes.
