Tweak Your Bass Tone Until It's Perfect!

From the beginning, BOSS has built the best pedals by adhering to these key principles: reliable aluminum die-cast bodies, pedal switches that withstand the 100,000-repetition durability test, FET switches to eliminate the clicking noise of conventional mechanical switches, non-slip rubber bases, easy-to-install battery compartments, LED indicators, and both battery and AC power. Only the very best components and circuitry are used in BOSS pedals. No corners are cut, no compromises are made - these pedals are built to sound great and take a pounding!

The BOSS GEB-7 is seven-band equalizer created specifically for the frequency range of the electric bass. The EQ bands can be boosted or cut up to 15dB, while a gain control also offers a +/-15dB range. Since the GEB-7's frequency range extends down to 50Hz, it's also great for adding depth and bottom end to acoustic guitars.

BOSS GEB-7 Bass EQ Pedal Features:

  • 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
  • Equalizer control: +/-15dB
  • Great for acoustic guitar applications
  • Nine-volt battery operation or use optional PSA-Series AC adapter
  • Input jack, Output jack, AC adapter jack
  • Five-year warranty

Not a One Trick Pony

I patched this into my keyboard pedalboard after the direct box. I use it to roll off low end so that the bottom end of the keyboard stage sound does not fight with the bass or drums. This make the keyboard poke through the stage mix without cranking the volume. If I'm playing by myself and want to sound huge (e.g., Jump), I bypass the eq and mission accomplished. When the volume DOES need a boost, I use the level control to control my stage volume without affecting FOH levels. This may be great for a bass, but it is so handy for my keyboard that I'm not even tempted to try it on my bass.

Makes a big difference in the sound in a good way. Brings presence and low end to your bass sound. I keep mine on at all times. I like this eq pedal compared to others because it has an overall volume slider.

Works Well

I looked at Bass controls. This was one of my choices. Ryan Clapper my tech felt this would do what I want. The pedal really has a strong effect on the electric bass sound. I use it with a wireless system. Quiet operation and makes a very significant difference for sound. Thank you

Excellent Pedal

This pedal is really fabulous, gives my bass more power and a real sharp tone, of course it's a boss!! .You'll really feel the difference when using this pedal. I only regret not buying this pedal before.

Sweetwater Advice

Jared Kalish

Have you ever wanted to change your EQ settings on the fly without having to run back to your amp? This pedal allows you to have a way to stomp in for a solo section or quick song change without having to fumble with your amp's EQ. I've been using it with a smiley face curve to punch in when I rip some funky slap lines. Really a great box.
