Wampler Plexi-Drive Settings Guide
The Wampler Plexi-Drive is a Marshall Plexi-in-a-box pedal — designed to replicate the character of a cranked 1959 Super Lead at manageable volumes and prices. It captures the mid-forward, harmonically complex overdrive character of the Plexi circuit without requiring a vintage 100W amp at full volume. Volume, Gain, Bass, and Treble controls allow full EQ shaping. The Plexi-Drive Deluxe version adds a Bright switch and a Pre control for additional versatility.
The best Wampler Plexi-Drive settings start with: Volume at 6/10, Gain at 6/10, Bass at 5/10, Treble at 6/10. Adjust from there based on your amp, guitar, and room volume. For Classic Rock: Volume 6/10, Gain 6/10, Bass 5/10, Treble 6/10.

Settings by Genre
Moderate Gain for the classic Plexi crunch — mid-forward, warm, harmonically rich. The Plexi-Drive at Gain 6 produces the kind of overdrive that defined 1960s and 70s rock: not a saturated modern distortion but a complex, dynamic crunch where note articulation remains clear within the overdrive.
Lower Gain for pick-sensitive blues-rock overdrive. Treble at 7 adds the bright, cutting edge that Page and Beck used for lead lines. Gain at 4 keeps the pedal in the "pushed amp" territory rather than outright distortion.
Higher Gain for more aggressive hard rock tones. The Plexi-Drive at Gain 8 moves toward distortion territory while retaining the Marshall character — not a modern metal sound, but aggressive classic rock that suits heavy riffing.
Low Gain, high Volume as a Marshall-character clean boost. Into a slightly saturated amp, the Plexi-Drive at low Gain pushes the amp while adding the Plexi's characteristic mid-frequency emphasis. Useful as a solo boost that changes the amp's EQ character as well as volume.
Tips & Common Mistakes
- The Plexi-Drive works best into a clean or slightly saturated amp — its character comes from adding the Plexi's preamp voicing in the pedal, then letting the amp handle power amplification. Into an already-distorted amp it stacks in conventional ways but loses the specific Plexi character.
- The Bright switch (Deluxe version) changes the high-frequency response significantly — OFF produces the warmer, darker Plexi character of vintage amps; ON adds the brightness of new-condition vintage caps. Experiment with both.
