The PlexiPre Classic Overdrive is a 5-stage JFET circuit crafted to capture the unmistakable overdrive and distortion roar of an early Marshall® Plexi™ amplifier. It cleverly combines two parallel stages—one channel bright and biting, the other smooth and full-stack mellow. A Master Volume control lets you crank up the gain without sounding like a riot outside your door. In between blending these gain stages and the Master Volume sits a Baxandall active 3-band EQ, delivering that classic amp tone stack feel with enough sonic flexibility to mate perfectly with any guitar and amp setup.
