Mark IIC+/++ Clone
In conjunction, they can boost or cut frequencies at 80Hz, 240Hz, 750Hz, 2200Hz and 6600Hz.
The GEQ can be engaged in EQ Out, EQ In, and EQ Auto Modes, and can be footswitched.
EQ Out has the GEQ Off, EQ In has the GEQ In for Lead and Clean Modes, and EQ Auto engages the EQ when Lead is engaged.
