This is the next addition to the bass EQ pedals from Boss/Roland. The pedal can adjust your bass tone to the frequencies that your desire or want taken down or out. This was to replace the Boss GE-7B. For the most part the tone and style is unchanged. The frequencies have however take a better turn for the bass guitarist. The frequencies are now at 50Hz, 120Hz, 400Hz, 500Hz, 800Hz, 4.5kHz and 10kHz which means they're not spaced at octaves anymore. This gives the most critical frequencies of 400hz-500hz two separate sliders for more overall control of tone.

The most critical frequencies for the guitar are the 800hz where as the most important to the bass guitar are between 400hz and 500hz. This newer EQ pedal addition tackles that dilemma better than the previous Boss Ge-7B. You now have a much more usable EQ pedal design specifically for the bass guitar.

This pedal works well with any bass guitar or bass amp that needs some major or minor EQing adjustments. The pedal can be a bit noisy and that is because it is a booster pedal which adds distortion to the mix. So that can be tamed depending on how much or how little of the sliders that you use. The level will have the most effect of noise to your rig.


At new these pedal come in right at around $100, which isn't bad for a good EQ pedal for bass guitar. The pedal is a must for someone who may have an older bass amp or an amp that doesn't highlight the right frequencies that you would like. This is a cheap alternative to buying a whole new rig. I would recommend this pedal to any bass player who needs to fine tune his sound to where it fits best in his or her band mix.
