The PlexiPre Classic Overdrive is a 5 stage JFET overdrive circuit designed to emulate the sound of an early Marshall® Plexi™ amplifier's overdrive/distortion tones. PlexiPre uses two stages in parallel, one for the bright channel, and one for the normal channel (which emulates the tone of a full stack) as well as a Master Volume to allow for higher gain settings without inviting the cops to your home. The PlexiPre also adds a Baxandall active 3-band eq between the summing of the gain channels and the Master volume, to allow for a familiar amp-like tone stack and enough eq range to work with any guitar and amp.

Controls

• Bright - Controls the Gain of the Bright Channel

• Normal - Controls the Gain of the Normal Channel

• Master - Controls the overall output level of the PlexiPre

  • The master volume allows you to turn the individual channels up to optimal breakup and then adjust the output volume to a tolerable level.

• 3-Band Active EQ - used to boost or cut 3 frequency ranges.

  • Bass

  • Middle

  • Treble

NOTE: In active equalizers, 12 noon, or halfway is the "zero" point.

• Turning the knobs clockwise, boosts the output of the selected band

• Turning the knobs counter-clockwise cuts the output of the selected band
