Wave Arts Tube Saturator 2Tube Saturator 2 is a super accurate circuit simulation of a tube pre amp with analog EQ, which can be overdriven gently for warming effects, or cranked for fat distortion. Like its predecessor, Tube Saturator, TS 2 is based on circuit simulation technology to capture every nuance of an analog circuit. The circuit consisting of the individual tubes, resistors, and capacitors is converted into a mathematical system of equations which is numerically
