GEB-7 Bass Equalizer

The Boss GEB-7 Bass Equalizer is a 7-band graphic equalizer specifically voiced for bass guitar, providing ±15 dB of boost or cut at 50 Hz, 120 Hz, 400 Hz, 500 Hz, 800 Hz, 4.5 kHz, and 10 kHz. The center frequencies and constant-Q filter design allow each band to be adjusted independently with minimal interaction, making precise tone shaping easier. A dedicated Level slider lets you match or boost the overall output, making the pedal useful as both an equalizer and a clean level boost. The GEB-7 is suitable for correcting room acoustics, shaping instrument character, enhancing slap techniques, or creating amp-like EQ curves.
