Equalisation changes the level of selected frequency regions without intentionally adding modulation or time-based effects. Graphic EQ divides the spectrum into fixed bands, parametric EQ allows frequency and bandwidth to move, and simpler designs provide broad bass, middle and treble shaping. Available boost or cut, centre frequencies, filter width and overall output level determine whether the pedal makes corrective, tonal or gain-driving changes.
Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.
