What we say:

Mixing the best of the 'Muff' tones with a circuit that doesn't lose all of your bass frequencies, Electro Harmonix's Bass Big Muff Pi is one of the greatest bass drive/fuzz pedals out there without question.

Bass players have always used the Big Muff to get an excellent fuzzy grind but have always lamented the loss of low-end they would have to tolerate. Until now! This bass-specific Muff keeps all of the low end thump right there with a bass boost switch and also a dry switch to bring your non-fuzzed sound back in a little for coherence and fidelity.

This is totally filthy and preserves the sonic bottom of your sounds whilst simultaneously smashing it to bits.


  • True bypass
  • Tailor your drive/distortion sound with sustain, tone and volume knobs
  • A dry switch that mixes your dry bass with the Bass Big Muff Pi's distortion
  • A bass boost EQ switch that reintroduces your low frequencies when tone is set for high frequencies
  • Based on the Russian Big Muff
  • Tough and compact die-cast chassis
  • 9-volt battery included
  • Optional 96DC-200BI power supply available

Great item, great service.

Can get a wonderfully dirty sound from this pedal. Heavy metal heaven.

Good pedal. Does what is says on the tin.

Derek M. - 27/11/2018

Wanted a good overdrive pedal & got an amazing one.

John B. - 24/3/2018

Really good tones. Worth watching youtube review before purchase.

The EHX Bass Big Muff Pi in one word; MONSTEROUS! I generally D.I straight into the desk & it has really beefed up my bass sound like a herd of giant migrating caribou (are they classed as beef? ^_^). You can really sculpt the tone from pleasing levels of fuzz to all out industrial grit, alter wet/dry levels & boost the bass even more if you're feeling rebellious (& the neighbours are out). I can't describe how well it's sound moulds to the bass frequencies- almost like a compression...just pick one up & try it. For the price you can't go wrong. One minor quibble is that the activation switch is very noisy & clicky...when compared to the ultra-quiet Boss pedals anyway at least.

This was a birthday present for my nephew. I think it must be good as we don't see him much but we certainly hear him.
