The Boss GEB-7 is a seven-band equalizer created specifically for the frequency range of the electric bass. Since the frequency range extends down to 50Hz, the GEB-7 is also great for adjusting depth and bottom end of an upright bass with pickups.
Classic BOSS Design
The GEB-7 can run off of a single 9V battery or an optional external 9 VDC power supply. The electronics are encased in BOSS’s iconic durable metal housing with a non-slip rubber base. The battery compartment can be easily accessed by unscrewing the thumbscrew at the front of the pedal. This pedal utilizes a buffered bypass for silent switching and driving long cable runs even while the pedal is disengaged.
