The illustration below shows the output signal and distortion just below the clipping limit, and the
clipped output signal and accompanying distortion components.
In the lower waveform it can be seen that distortion consists of both even and odd overtones, with
the second overtone as most significant. Once again this brings to mind the characteristics of the
electron tube amplifier with soft, rising overtones, strong signal and rapidly diminishing overtone
spectrum.
The overdriven signal (left portion of illustration) recovers momentarily from the clipping mode, the same
condition found in hard-coupled operation amplifiers.

OVERDRIVE
The Output Mixer combines two signals, a clean signal from the Master Amplifier and a
saturated signal from a saturation stage. The saturation stage is overdriven successively
with the knob from clean to full saturated signal. This gradually produces increasing distortion,
soft clipping, and with hard overdriving successively changes the operating point (as in a
triode) to cause increasingly unsymmetrical clipping. This unsymmetrical clipping results in
the retention of more so-called musical material that would otherwise be lost in symmetrical
clipping.
property found in electron tube amplifiers, but lacks the characteristic recovery time from clipped to linear
