Keep your bass sound under control or unleash it for new frequencies with the BOSS GEB-7 Graphic Equalizer.

The equalizer pedals are essential equipment for a better sound, so that they are only concerned with the music. The BOSS GEB-7 is the secret weapon of bass players around the world for a defined and powerful sound, exploiting the full sonic potential of your instrument.

Easy to use, the GEB-7 lets you customize your bass guitar sound, giving it greater quality, consistency and individuality. The seven sliders control frequency ranges from 50Hz to 10 kHz, the ranges used by this instrument, including those produced by five- and six-string basses. The visual layout of the cursors immediately shows the sound profile they are creating.

In addition to the individual sliders for each of the bands, there is also one dedicated to the general level, to add (boost) or remove (cut) some EQ gain.

With the GEB-7 you will be able to create a tone with greater quality, giving a new life and another sound dimension to your bass, while opening your sound to new aesthetic possibilities and musical styles, without having to change the bass model.

It is especially recommended for use with some instruments that are more demanding in their equalization, such as electro-acoustic basses, reducing the possibility of feedback in case of more complex amplification conditions.

For over 40 years, BOSS has produced the most iconic pedal models that have shaped the sound of some of the most important artists of recent decades. All of its products are recognized for their high strength and durability, thanks to a solid construction, capable of surviving the most demanding and intense stage conditions.

The BOSS GEB-7 Graphic Equalizer is a very versatile tool that should be part of the options of all bass players looking to create a solid bass sound, well defined and to their liking, with the bass they already have.
