The new Deluxe Bass Big Muff PI Distortion/Sustainer is the latest in the line of Electro-Harmonix bass specific effects. It delivers enhancements to the classic Bass Big Muff PI that are specifically tailored to the needs of the modern bass player and gives you more tone shaping options than ever before.


  • Pad on the input that's switchable between 0dB and -10dB ensures the pedal is optimized for use with both passive and active pickups
  • Blend allows a player to mix to taste the direct and distorted signals
  • Three outputs: a 1/4" effect out, 1/4" direct (buffered dry) out and XLR DI out give complete control of your output signal and sound
  • Foot-switchable crossover section with a variable low pass filter on the dry signal and a variable high pass filter on the distorted signal give bassists the ability to sculpt their sound
  • Crossover circuit, in conjunction with the Blend control, lets you keep the low-end clear and focused and the high-end bright and cutting
  • Built-in noise gate with an adjust threshold eliminates unwanted noise at any level
  • Tough and compact die-cast chassis
  • 9-Volt battery included
  • Optional 9.6DC-2000BI power supply available

Things You Will Get:


I would definitely buy this product again


I love this effects pedal. It can sound super clean, or as grungy as you want.



Awesome Bass Fuzz

Back to the Old-School!

Buy this pedal. Do it now!!!


Absolutely fantastic pedal. The distortion is creamy and beefy Think MUSE - Hysteria my new favorite pedal now.



The best fuzz pedal i've owned


Fantastic Pedal, does everything I need it to do and more! Fantastic for all your fuzz/distortion needs! A bassist must have!



Great fuzz pedal


#sweepstakes Does exactly as it should. Great fuzz tones for bass.



Great quality for the price


This pedal has some great tonal capabilities, seeing as you can control the low and high ends of the overdrive seperately. The noise gate is really handy in between songs and for sharp pauses. Over all for the money I haven't found a better overdrive. I pair it with a dark glass overdrive pedal and the two give me a fat amount of grit while still retaining musical tonality. I play metal with this pedal mostly.

Awesome Pedal


The infamous bass PI, on steroids. This pedal is a must have for any bassist. Great for solos and rock n roll. Have distortion from soft and creamy, to hard and in your face. This is a real hands on product review from [email protected] Sam Ash Indianapolis.
