This is a 7 band graphic equalizer pedal designed specifically for the bass guitar.
It has a wide frequency range over the 7 bands from 50Hz to10 kHz with each band having a wide 15dB boost/cut per band. This gives wide scope for shaping sound and eliminating unwanted feedback.
It is most useful for boosting the bottom end frequencies as you would expect from a bass pedal.
Overall, a good bass equalizer pedal
