Mesa Boogie Flux Drive Settings Guide
The Mesa Boogie Flux Drive is Mesa's dedicated overdrive/distortion pedal designed to drive the front end of tube amps or model the preamp character of Mesa amplifiers. Its JFET-based circuit covers transparent overdrive through thick distortion with a two-band EQ and a Contour control that shapes the mid-frequency response. Compact, well-built, and specifically designed to complement Mesa amplifiers.
The best Mesa Boogie Flux Drive settings start with: Gain at 6/10, Volume at 6/10, Bass at 5/10, Treble at 5/10, Contour at 4/10. Adjust from there based on your amp, guitar, and room volume. For Metal: Gain 8/10, Volume 6/10, Bass 7/10, Treble 6/10, Contour 7/10.

Settings by Genre
High Gain and Contour — the Flux Drive into the clean channel of a Mesa amp produces an approximation of the Mesa high-gain Rectifier character. Contour 7 scoops the mids for the modern Mesa metal voice. Bass 7 adds low-end weight. This is the most natural application — the Flux Drive was designed to push Mesa clean channels.
Moderate Gain, flat Contour — the Flux Drive for hard rock rhythm into any tube amp. At Gain 6 and Contour 4 the Flux Drive sounds more like a warm, musical distortion than a specifically 'Mesa' pedal. Its JFET circuit adds tube-like character to the gain stage.
Low Gain as amp push — the Flux Drive at minimal Gain and high Volume boosts the amp front end in a transparent, Klon-like application. The JFET circuit adds warmth to the clean boost. Contour at 3 (flat) preserves the amp natural mid character.
Maximum Contour with elevated Treble keeps low-tuned, extended-range riffing tight and cutting, while Gain stays moderate relative to the Metal preset to avoid excess mud at extreme low tunings.
Low Gain with Contour nearly flat keeps this pedal in warm, dynamic overdrive territory rather than the scooped high-gain voicing it is best known for, suited to touch-responsive blues-rock lead work.
Tips & Common Mistakes
- This pedal works best into a tube amp clean channel at moderate volume — it adds the preamp gain that the clean channel lacks. Into an already driven amp it layers additional saturation, which can produce indistinct, compressed tone at high Gain settings. For best results: clean amp plus this pedal at working Gain, rather than a driven amp with the pedal at low Gain.
- Because it was specifically designed to complement Mesa amplifiers, players using non-Mesa amps should not assume the Contour control behaves identically — audition the full range on your specific amp rather than defaulting to the Mesa-voiced presets.
- The JFET gain stage gives a warmer, more amp-like character than op-amp-based distortion pedals at equivalent Gain settings, worth comparing directly if switching from a more digital-sounding high-gain pedal.
- For a subtle always-on tightening effect rather than an obvious distortion, keep Gain low and use Contour alone to shape mid presence — a legitimate use case distinct from treating this as a dedicated high-gain pedal.
- Bass and Contour interact rather than stack cleanly — high settings on both together can produce a boomy, undefined low end, so treat them as a combined decision rather than two fully independent controls.

Mesa Boogie Flux Drive — Common Questions
Best starting settings for Mesa Boogie Flux Drive: Gain at 6/10, Volume at 6/10, Bass at 5/10, Treble at 5/10, Contour at 4/10. Adjust from there based on your guitar, room, and playing style.
For Metal: Gain 8/10, Volume 6/10, Bass 7/10, Treble 6/10, Contour 7/10. High Gain and Contour — the Flux Drive into the clean channel of a Mesa amp produces an approximation of the Mesa high-gain Rectifier character. Contour 7 scoops the mids for the modern Mesa metal voice. Bass 7 adds low-end weight. This is the most natural application — the Flux Drive was designed to push Mesa clean channels.
For Hard Rock: Gain 6/10, Volume 6/10, Bass 6/10, Treble 5/10, Contour 4/10. Moderate Gain, flat Contour — the Flux Drive for hard rock rhythm into any tube amp. At Gain 6 and Contour 4 the Flux Drive sounds more like a warm, musical distortion than a specifically 'Mesa' pedal. Its JFET circuit adds tube-like character to the gain stage.
Gain: Gain range from transparent boost through distortion. (Boost to Saturate). Volume: Output level. (Unity to Loud). Bass: Low-frequency EQ. (Cut to Boost). Treble: High-frequency EQ. (Dark to Bright). Contour: Mid-frequency contour — adds the Mesa scooped-mid character at higher settings. (Flat to Scooped)
