BOSS Equalizer GE-7

In addition to creating the desired tone, it also helps prevent feedback. A 7-band equalizer that can boost or cut frequencies between 100Hz and 6.4kHz. It's effective for proactive sound design, as well as for noise reduction and feedback prevention. The level control uses an independent amplifier system, prioritizing sound quality above all else. Connecting it after distortion will correct the overall sound quality, while connecting it before distortion will allow you to adjust the amount of distortion for each frequency band.
