The Cerberus features premium internal components, which are selected for low noise and superior tone. The exterior finish is a hard guitar grade polyurethane finish, which is silk screened and then baked to lock on the labeling and harden the clear coat. The Cerberus Tri-Mode overdrive provides three distinctive overdrive gain and clipping modes, as well as allowing you to carefully adjust both the input and output gain to perfectly tailor your pedal to your own unique personal sound! The green mode is a High gain rock mode. The blue mode is a medium gain blues mode. The red mode is a low gain rock mode.
