The most common guitar-tone question of all. Both add "dirt", but overdrive gently pushes your amp into natural breakup, while distortion generates its own heavier, more compressed clipping — independent of the amp.
| Overdrive | Distortion | |
|---|---|---|
| How it works | Soft-clips and pushes your amp into its own breakup — amp-dependent. | Hard-clips and creates the heavy tone itself — works even into a clean amp. |
| Gain amount | Low–medium. Dynamic, touch-sensitive, opens up when you dig in. | Medium–high. Thicker, more compressed, more consistent. |
| Best for | Blues, classic rock, pushing a tube amp, boosting a dirty amp. | Hard rock, metal, getting heavy from a clean or solid-state amp. |
| Feel | Reacts to your picking and guitar volume — very expressive. | More "set and forget" — stays heavy regardless of attack. |
