The Boss EQ-20 Advanced EQ is an all-purpose graphic equalizer pedal. Sound tuning can be handled on 10 bands using individual fader sliders for each one. This allows users to compensate for the environment they find themselves in and for various types of amplifiers, and can be used in conjunction with other effects pedals. A level switch is also built in to account for different setups, offering a 4 decibel boost depending on whether the connection is before the amp or in the effects loop. Up to 9 presets can be created and stored internally for later recall.
