The Electro Harmonix Triangle Big Muff Pi Guitar Effects Pedal is a faithful reissue of the original Version 1 Big Muff in all its glory. Though it is scaled-down to a pedalboard-friendly size, the Triangle Big Muff Pi produces that heavenly saturated tone that has featured on so many classic songs. From funk to grunge, there isn't a genre that remains untouched by the Big Muff's sound, and now you can get your hands on a rendition that stays true to its roots.

Vivid recreation

The EHX Triangle Big Muff Pi features a faithful recreation of the original 1969 era circuit, which takes your tone from glassy sparkling clarity to raucous overdriven fuzziness with sustain that endures for days, all whilst retaining a clear musicality that shines through. Across the top you'll find a trio of controls for Volume, Tone, and Sustain. The Volume pot sets the output level, whilst the Tone allows you to sweep from high treble to rumbling bass. Depending on whether you want more of a sweet high-end character or a stirring hard rock inspired edginess you simply need to attenuate the control knob. The Sustain control allows you to adjust the sustain and distortion, again taking you from subtle to an epic in-your-face wall of noise.

Gig-ready construction

The Electro Harmonix Triangle Big Muff Pi Guitar Effects Pedal is built to take anything thrown its way during performances. The diminuitive size makes it ideal for slotting discreetly into any pedalboard setup. The smooth response of the control knobs is matched with a reassuringly sturdy footswitch, whilst a bright LED ensures that you can easily monitor the pedal's status on the darkest of stages. The pedal can be powered by using a 9V battery or an optional 9VDC AC adapter.

Whether you're looking for some classic prog-inspired fuzziness or want to reignite the glory of the grunge days, then the Electro Harmonix Triangle Big Muff Pi Guitar Effects Pedal is as close as you can get to the original without forking out considerably more money.
