The Instruō tanh[3] is a three channel waveshaper, limiter, overdrive, and feedback controller.

Each channel of the tanh[3] takes a signal input and outputs the hyperbolic tangent function (tanh (x)) for that input signal.

… In more musical terms, tangential distortion is a form of soft clipping which can produce signal amplitude limiting via analogue waveshaping. Driving a hot audio signal into it will add warm overdrive.

Raw waveforms will be subtly shaped; softening or adding harmonic content based on input amplitude.

Understanding what the tanh[3] does to a signal, both mathematically and sonically can be hard to explain, but it essentially adds curves
to signals.

For many Max/MSP and/or PD users, the [tanh~] object may be familiar and is likely a much used secret weapon in many contexts.

 

Note: This is a used item, and while it is guaranteed to be fully functional it is almost sure to also contain "rack rash" on the mounting holes and have some minor scratches on the panel from use. It will include a ribbon cable, m3 screws, and a box, but not the original box.
