Xotic BB Preamp Settings Guide

The Xotic BB Preamp is a two-band EQ overdrive/preamp based loosely on the Marshall Bluesbreaker circuit — it covers clean boost through mid-gain overdrive with a bass and treble boost/cut. At low Gain settings it functions as a transparent preamp; at high Gain it delivers a warm, amp-like overdrive particularly well-suited to semi-hollow and single-coil guitars.

The best Xotic BB Preamp settings start with: Gain at 5/10, Volume at 6/10, Bass at 5/10, Treble at 5/10. Adjust from there based on your amp, guitar, and room volume. For Blues: Gain 6/10, Volume 6/10, Bass 5/10, Treble 5/10.

Settings by Genre

Blues
Gain6
Volume6
Bass5
Treble5

Moderate Gain with flat EQ — the BB Preamp at Gain 6 produces a warm, organic overdrive that preserves the guitar's voice. Flat Bass and Treble let the amp's natural EQ character come through the pedal. This setting stacks well with a TS-style mid-boost pedal in front.

Clean Boost
Gain2
Volume8
Bass5
Treble6

Near-unity Gain, high Volume — the BB Preamp as a clean boost and presence enhancer. Treble at 6 adds the articulation and sparkle of a driven preamp without audible saturation. Used to push an amp from clean to edge-of-breakup.

Classic Rock
Gain7
Volume6
Bass6
Treble5

Higher Gain with Bass boosted slightly — the BB Preamp at Gain 7 produces warm, full overdrive suitable for classic rock rhythm playing. Bass 6 adds low-end body to the saturated signal. Keep Treble at 5 to prevent the high-gain setting from becoming harsh or thin.

Country (bright, low gain)
Gain2
Volume7
Bass3
Treble7

Low Gain with Bass cut and Treble pushed suits Telecaster-style bright, articulate rhythm playing, staying closer to a boosted clean tone than an overdrive.

Indie / Alternative (semi-hollow)
Gain5
Volume6
Bass5
Treble5

A moderate, flat-EQ setting suits semi-hollow guitars particularly well, adding warmth without fighting the natural resonance those instruments already provide.

Tips & Common Mistakes

  • This pedal sounds best with the Volume set so that it pushes the amp slightly when engaged — not just at unity with the amp. At unity gain it functions as a tone shaper; slightly above unity it begins to interact with the amp front end and produces the most musically interesting results.
  • Being loosely based on the Bluesbreaker circuit, this pedal shares family resemblance with other Bluesbreaker-derived designs — comparing it directly against those alternatives is worthwhile if the specific voicing here does not quite match what is expected.
  • Semi-hollow and single-coil guitars are specifically where this pedal is described as excelling — solid-body humbucker guitars will still sound good, but the pedal warmth complements the resonance of hollow and semi-hollow bodies particularly well.
  • The two-band EQ is simpler than a three-band design, which makes it faster to dial in but offers less fine control than pedals with a dedicated Mid control — a worthwhile trade for players who want speed over deep tone-shaping.
  • For a subtle always-on texture rather than a switchable overdrive, keep Gain low and Volume near unity, using the pedal purely for its tonal coloration rather than as a distinct gain stage.
