Gravity amp settings — Zoom G3Xn
The John Mayer guitar tone for “Gravity”, dialed in for a Zoom G3Xn with a Squier Bullet Stratocaster. Studio version, Continuum (2006)
Fender Stratocaster (Custom Shop 'Big Dipper' pickups) → Klon Centaur (always-on low-gain boost) → Ibanez TS-808 (stacked for leads) → Two-Rock Custom Reverb Signature (Dumble-style clean amp)
| Knob | Setting (0–10) |
|---|---|
| Gain | 3 |
| Bass | 5 |
| Mid | 6 |
| Treble | 6 |
| Presence | 5 |
| Reverb | 2 |
| Master | 7 |
01Zoom G3Xn Compressor (ZNR Comp or Comp)
Light compression for studio polish and sustain — always on
02Zoom G3Xn Tube Screamer (TS808 or TS Drive)
Set as transparent boost, not for distortion — pushes the clean amp slightly for harmonic richness
The Two-Rock is a Dumble-style amp with massive clean headroom and touch sensitivity. The G3Xn's Fender Deluxe Reverb model gets closest — select it and keep gain low (3) to stay clean. The Klon's 'always-on boost' role is handled by the TS808 model at very low gain (2) with level raised — this adds subtle compression and harmonics without actual dirt. Mayer's Big Dipper pickups are warmer than stock Bullet ceramics, so roll your tone knob to 7 and keep treble at 6 to avoid brittleness.
