The Boss GEB-7 Bass Equalizer Pedal is compact but features a wide frequency response from 50Hz to 10kHz. It has 7 sliders, 3 of which cover the critical midrange (400Hz, 500Hz, and 800Hz) where the character of the bass sound is determined. Each slider on the Boss GEB-7 equalizer pedal boosts or cuts over a +/-15dB range, allowing for substantial tone-shaping capability.

The Boss GEB-7 is seven-band equalizer pedal created specifically for the frequency range of the electric bass guitar. Since the frequency range extends down to the 50Hz range, the GEB-7 is also great for adding depth and bottom end to acoustic guitars.
