BOSS GEB-7 Bass Equalizer Pedal

The Boss GEB-7 Bass Equalizer pedal is compact in size but features a wide frequency range—from 50Hz all the way up to 10kHz. It has seven sliders, three 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.
