CARAVAN is a jFET distortion using tube amplifier circuitry. Design solutions have been applied in which the field-effect transistor imitates the behavior of a vacuum tube, which saturates the sound with even harmonics, acquiring a warm "tube" sound.
In addition to the classic gain, CARAVAN has an additional gain,
which controls the clipping level of the last stage. Using various combinations of these controls, you can vary the nature of the overdrive from light crunch to a heavy growl over a wide range.
To ensure good signal dynamics (headroom), an increased supply voltage is used - 33 volts,
which is generated by the internal boost converter 9-33 V.
