Description
The Electro-Harmonix Op-Amp Big Muff Pi Distortion/Sustain Pedal is a reissue of a classic fuzz pedal from the 1970s. It aims to give you the iconic and sustaining distortion of that era. Three main controls are at your disposal including a volume knob for overall level, a tone knob to shape your timbre, and of course the fuzz knob with which you can introduce sweet distortion into your signal.
The original pedal relied on op-amps rather than transistors to achieve its signature, needling timbre. This pedal aims to recreate that original V4 circuit as faithfully as possible even as it adds a couple of tweaks to the design. For instance, the tone switch, which takes the tone knob out of the circuit altogether, no longer affects your overall output level. This is a departure from earlier iterations.
The Op-Amp Big Muff Pi utilises true bypass circuitry, to keep your tone pristine when it is bypassed. The pedal ships with a 9V battery, which can be replaced by unscrewing the backplate and accessing the battery therein. It also works with a 9V AC power adapter, which is available separately.
Key Features:
- Volume Knob: This sets the overall the output level.
- Fuzz Knob: This knob adjusts the amount of sustain and distortion.
- Tone Knob: This control facilitates a range of sounds, from high treble to deep bass. As you turn the knob clockwise, the treble increases and bass decreases.
- Tone Switch: This switch removes or adds the tone control from the circuit. This switch has been improved over the original Op-Amp Big Muff, as now the volume remains the same in both positions.
- Bypass/Engage Footswitch: The Footswitch toggles between effect and bypass modes.

While a well made pedal it seemed to not want to play nice with other pedals on my board and was hard to stack but results may vary. For what it does do right is that classic pumpkins sound and for that alone it is fantastic just dont expect it to deviate far from that sound tonal wise.Read more Read less
