Electro Harmonix Deluxe Bass Big Muff Pi 2 Bass Fuzz Pedal

The Electro Harmonix Deluxe Bass Big Muff Pi 2 takes the legendary dual op amp Big Muff circuit and supercharges it for modern bass players. Packed with flexible tone shaping, extended low-end response and pro-level connectivity, it delivers everything from subtle grit to apocalyptic fuzz while keeping your fundamental solid and defined.

At its heart, this pedal serves up the classic midrange grind and near-infinite sustain that made the Big Muff a staple, but adds a powerful BLEND control, noise gate and a unique CROSSOVER section so you can sculpt your fuzz around your playing style. Whether you are holding down the low end in a heavy band, adding texture in the studio or using it as a momentary blast of chaos on stage, the Deluxe Bass Big Muff Pi 2 is designed to slot straight into serious bass rigs.

With expanded I/O including a dedicated DI output and a separate buffered direct out, it is equally at home on stage and in the studio. A selectable input pad keeps high output basses in check, while the flexible bypass and latching/momentary footswitch behaviour let you use it as either a traditional always-on effect or a quick-hit special effect. This is a fuzz pedal built for bassists who want more control, more punch and more sonic options.

Classic Big Muff Fuzz, Optimised for Bass

The Deluxe Bass Big Muff Pi 2 uses a unique Big Muff circuit built around two dual op amps, delivering the saturated sustain and aggressive character players expect, but tuned for extended low-end. VOLUME, TONE and SUSTAIN controls give you instant access to everything from smooth, singing drive to thick, chainsaw fuzz, all while preserving the power and presence of your bass in a mix.

Blendable Clean and Fuzz Tones

The BLEND control lets you dial in the perfect mix of clean and distorted signal. Keep more of your dry tone for punchy, articulate lines with added edge, or push the fuzz forward for gnarlier, more extreme sounds. Being able to balance clean low-end with saturated top-end means you can stay tight and defined, even with the most over-the-top fuzz settings.

Powerful Crossover Tone Shaping

The footswitchable CROSSOVER section splits your signal into two paths for advanced tone sculpting. A high-pass filter shapes the signal feeding the fuzz circuit, while a low-pass filter shapes only the clean path. With the HPF and LPF controls you can create a bright, cutting fuzz tone on top of a huge, clean bass foundation, or fine-tune how much low-end hits the fuzz for tighter, more controlled distortion.

Stage and Studio Ready Connectivity

An expanded I/O section makes the Deluxe Bass Big Muff Pi 2 a flexible hub in any rig. A selectable input pad helps tame hot pickups, while the standard input and output jacks are complemented by a low impedance XLR DI OUTPUT for sending your effected signal straight to a mixer or interface. The DIRECT OUT provides a buffered, clean version of your original signal, ideal for parallel processing or sending a separate feed to front of house or recording gear.

Flexible Footswitch and Noise Gate

The true bypass footswitch offers both latching and momentary operation, so you can tap it for normal on/off use or hold it for short bursts of fuzz. A built-in noise gate tightens up your sound by clamping down on unwanted hiss and hum when you are not playing, keeping your rig quiet between notes and making high gain settings far more manageable on stage.

• Dual Op Amp Big Muff Circuit - A unique Big Muff design using two dual op amps delivers the classic midrange grind and massive sustain, optimised for bass with extended low-end response so your sound stays thick and powerful.
• Blend and Crossover Controls - The BLEND knob and powerful CROSSOVER section let you mix clean and fuzz signals and split them across high and low frequencies, giving you everything from subtle grit under a clean low-end to searing top-end fuzz over a solid bass foundation.
• Expanded I/O with DI and Direct Out - Alongside the standard input and output, the low impedance XLR DI OUTPUT sends your effected tone straight to a mixer or interface, while the DIRECT OUT provides a buffered, unaffected signal for parallel setups and flexible routing.
• Latching/Momentary Footswitch with Noise Gate - Use the footswitch as a standard latching on/off control or hold it for momentary blasts of fuzz, while the built-in noise gate keeps high gain settings tight and controlled by eliminating unwanted noise between notes.
