TK-Lizer 2 is an update from TK Audio to their excellent TK-Lizer EQ unit. Just like its predecessor, the equalizer is based on the same Baxandall tone control circuit. An additional 6 HPF frequencies have been added to the revised version of the unit. Also, TK-Lizer 2 features updated knob design, better frequency response and much lower ouput distortion. All the familiar features remain intact, and the sound remains immaculate.
