Overdrive pedals use soft or hard clipping to add breakup, harmonic density and sustain while usually retaining more pick response than heavier distortion. A low-gain circuit can act as an always-on preamp or push an amplifier; a higher-gain design may supply its own compressed voice. Gain, tone, bass, presence, output and clipping options decide how the pedal stacks with other drives. The same pedal can sound open into a clean valve amp and congested into a saturated preamp, so judge it at the level and with the speakers it will actually meet.

Designed or voiced to retain low-frequency information and headroom with bass guitar or other low-register sources. Controls may centre on clean blend, low-end EQ, compression or drive.
Runs from replaceable or rechargeable batteries as well as, or instead of, an external supply. Battery life depends on current draw, wireless operation, displays and how often the unit is left connected.
Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
