Tube Saturator 2 from Wave Arts is a plug-in that employs circuit simulation technology to emulate the analog schematic often found in tube preamplifiers. It models two common cathode preamp stages, with selectable 12AX7 and 12AU7 tube circuits. A Baxandall 3-band EQ can be placed pre or post saturation and both the EQ and saturation circuits may be bypassed. Additionally, a 2x oversampling mode provides attenuation of aliased distortion harmonics. The software is designed to provide everything from warmth to full-on drive for distortion.
