The GE-7 7-Band Graphic Equalizer from BOSS gives you precise control over your sound, coupled with the convenience and accessibility of a compact pedal. Seven frequency bands, from 100 to 6400 Hz, are controlled by seven mini-faders, each of which can boost or cut the corresponding frequency by up to 15 dB. The pedal can be used to dial in brighter, more biting tones for cutting leads, or to control feedback by bringing down problematic frequencies.
