Builds on the foundation of the original Plexi-Drive but gives you considerably more control to shape your tone | The 3 band active EQ, additional brightness control, and perfectly voiced pre-gain booster, help get almost any Plexi tone from virtually any amp | The unique gain structure can cover everything from Vintage ’68 style Plexi tones to the all out massive rock tones of a JTM-45 cranked to ten, or even eleven | The bass boost emulates the low-end thump of a 4×12” cabinet at the flick of a switch, and you can dial in your low end for lower volumes | The bright switch adds high end sparkle-which makes changing from bright to dark guitars (and amps) a breeze | Features a one knob, pre-gain boost soft click switch that is voiced like a certain green overdrive to help push your leads into thick, creamy overdrive
