This is followed by the Distortion unit, which in the TC-1 variant has similar controls as the Overdrive complemented by a Lo / Hi voicing switch, while in the high-gain version of the TC-2 this circuit is equipped with gain, volume and three-band corrections with semi-parametric centers, which "two".
