Electro-Harmonix Bass Big Muff Pi 2

The Legend Returns - A modern revival of classic fuzz tones, optimised for bass

The Bass Big Muff Pi 2 from Electro-Harmonix resurrects a long-lost dual op-amp Big Muff circuit and tunes it specifically for low-end instruments such as bass guitars, while retaining the signature sustain and midrange grind that have made the Big Muff legend endure. It delivers aggressive yet musical fuzz with enhanced clarity and punch.

Versatile and expressive control layout

Equipped with intuitive controls and performance-friendly features, the Bass Big Muff Pi 2 lets players shape their fuzz with precision. Classic Volume, Tone and Sustain controls provide the familiar Big Muff voice, while the added Blend knob mixes clean and fuzz signals to preserve low-end fundamentals. A Bass Boost switch enhances low-frequency energy when needed, so your sound stays full even with brighter settings.

Flexible footswitch and rugged build

A soft footswitch offers both conventional latching and momentary operation, allowing for bursts of fuzz mayhem on demand. True bypass routing ensures your clean signal remains uncoloured when disengaged. Housed in a compact, pedalboard-friendly enclosure, the Bass Big Muff Pi 2 is built for touring, lounge gigs or studio work.

3. We always refund the payment according to how the original purchase was made and aim to do so within 72hrs of the return being received by us.

4. Returned goods are liable for a restocking fee of 15% towards handling and repackaging if the order is not returned in its original, unopened packaging. This charge will be subject to our inspection of the returned goods.
