The gentlest and the wildest ends of "dirt". Overdrive softly pushes your amp into natural, dynamic breakup; fuzz is the most extreme, squared-off clipping there is — thick, saturated and often deliberately raw.
| Overdrive | Fuzz | |
|---|---|---|
| How it works | Soft-clipping — nudges the amp into its own breakup, amp-dependent and touch-sensitive. | Extreme, near-square-wave clipping generated by the pedal itself — a sound of its own. |
| Gain / saturation | Low–medium; dynamic and open, cleans up as you back off. | Very high, compressed and thick — from vintage splat to a wall of sustain. |
| Feel | Reacts to picking and guitar volume — expressive and amp-like. | Big and saturated; some vintage fuzzes clean up with the volume knob, many do not. |
| Best for | Blues, classic rock, boosting a dirty amp, edge-of-breakup rhythm. | Psychedelia, stoner/doom, big leads, Hendrix and Gilmour-style textures. |
| Examples | Tube Screamer, Klon, Blues Driver, OCD. | Fuzz Face, Big Muff, Tone Bender. |
Overdrive soft-clips and pushes your amp into its own natural, dynamic breakup — it is expressive and amp-dependent (blues, classic rock). Fuzz is the most extreme dirt: heavy, near-square-wave clipping generated by the pedal for a thick, saturated sound of its own (psychedelia, stoner, big leads). Overdrive reacts to your touch; fuzz is a bold, characterful effect.
