Pre-Owned Boss GEB7 Bass Equalizer Pedal

The Boss GEB-7 Bass Equalizer is a low-end sculpting tool that gives bassists serious control over their sound—whether you're carving out mids for slap, fattening up fingerstyle tones, or cutting through the mix with surgical precision. Built specifically for bass guitar, the GEB-7 covers the entire low-frequency range with punch, clarity, and headroom to spare.

With seven bands of active EQ, including a sub-friendly 50Hz slider and extending up to 10kHz, the GEB-7 allows fine-tuned adjustments across the full bass spectrum. Each band offers ±15dB of boost or cut, giving you incredible flexibility to shape your tone to any genre, room, or amp rig. It also works beautifully for 5-string and extended range basses, where control over those sub-frequencies becomes essential.

The onboard Level control lets you use the GEB-7 as a clean boost, solo lift, or to balance your signal after heavy EQ cuts—making it a powerful tool in both live and studio environments. Its rugged Boss enclosure is built to take a beating, with noise-free performance and true dependability night after night.

This pre-owned unit has been fully tested and approved by the Musicmaker tech crew. It’s in excellent condition, with only light cosmetic wear and years of tone-shaping life ahead.
