Used Demonfx Gravity

The Demonfx Gravity is a dual-channel overdrive that pays homage to one of the most famous "tone recipes" in modern guitar: the combination of a TS10-style Tube Screamer and a Klon Centaur-style circuit.

The name is a direct reference to the signature live lead tones of John Mayer, particularly on songs like "Gravity" and "Belief," where he stacks these two specific circuits to create a thick, mid-rich "wall of sound."

Dual-Channel Layout

The pedal is split into two independent sides that can be used separately or stacked together:

• Side A (Left - TS10): Modeled after the late-80s Ibanez TS10. It features Drive, Tone, and Level knobs. It includes a Lows toggle switch to adjust the bass response, addressing the "thinness" some players find in standard Tube Screamers.
• Side B (Right - K-Overdrive): A Klon Centaur-style circuit with Gain, Treble, and Output controls. It features a Clipping toggle that lets you choose between Germanium (vintage, compressed) or Schottky (more headroom, modern) diodes.
