The 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.

• 50Hz to 10kHz frequency range specifically designed for bass
• Full range response, even for five- and six-string basses
• Can be used as a "boost" or "cut" pedal using the level control knob
• Great for electric-acoustic bass applications
• AC adaptor or 9V battery operation
• BOSS five-year warranty
