Long revered for its sweet singing tone and violin-like sustain, the classic three-knob Big Muff Pi has helped define the sound of rock guitar for over 40 years. Now, weve added some extras for those who crave more sound shaping control. Introducing the Deluxe Big Muff Pi. It delivers all the classic sounds of the original NYC Big Muff Pi, plus more.

• Adjustable Attack control adds punch to your single notes and chords
• Switchable Bass Boost for added bottom when you want it
• Expression Pedal input lets you sweep the mids in real time
• True bypass for maximum signal path integrity

CONTROLS

VOLUME Knob
Works as a master volume control for the entire pedal.

TONE Knob
Provides a range of sounds from high treble to deep bass. As you turn the TONE knob clockwise, treble increases and bass decreases.

SUSTAIN Knob
As in the original Big Muff Pi, adjusts the amount of sustain and distortion.

BASS BOOST/NORMAL Switch
When set to NORMAL, the Big Muff circuit is identical to our NYC Big Muff that we currently manufacture. Flip the switch up to BASS BOOST and the volume level of bass frequencies through the Big Muff circuit increases. Although the BASS BOOST function can be subtle it is most useful when TONE is set above the center, 12 oclock position.

ATTACK Knob
Is a volume control for the Attack effect. As you turn the ATTACK knob clockwise the Attack volume increases. Turn ATTACK all the way down (fully counter-clockwise) to turn Attack off.

The Attack signal path runs in parallel to the Big Muffs circuit. The function of the Attack circuit is to enhance the sound of your picking by applying 2 carefully chosen bandpass filters to the input signal followed by a volume expander that ensures your pick attack is louder than the sustained portion of the note. The Attack signal is not clean; it is usually very gritty but not nearly as distorted as the Big Muff circuit.

GATE Knob
Turning GATE clockwise raises the Gate threshold requiring greater input amplitude to open the noise gate, allowing your notes to be heard and your instrument to pass through. Turn the GATE knob down all the way, to fully counter-clockwise, to disable the noise gate.

MIDS LEVEL Knob
When MIDS is engaged (LED near MIDS Footswitch is lit) the MIDS LEVEL knob either boosts or cuts up to +/- 10dB, at the frequency set by the FREQ knob located below it. Turn MIDS LEVEL clockwise from its center 12 oclock position to boost the center frequency. To cut, turn MIDS LEVEL counter-clockwise from the 12 oclock position. This knob has a notch near the 12 oclock position to help identify the center of the knobs travel. In the center position, MIDS EQ is flat; it does not boost or cut. The MIDS LEVEL knob has no function when MIDS is bypassed (LED near MIDS Footswitch is off).

MIDS FREQ Knob
Sets the center frequency of the MIDS EQ circuit ranging from 310Hz to 5.0kHz. To hear the range of the MIDS FREQ knob, turn the MIDS LEVEL knob up past 3 oclock, make sure MIDS is enabled (LED near MIDS Footswitch is lit), then play your instrument while turning the MIDS FREQ knob. This knob has no function if either the MIDS section is bypassed (LED near MIDS Footswitch is off) or the MIDS LEVEL knob is set to its center position.

The MIDS FREQ knob can be controlled by an external expression pedal or control voltage (CV). Connect the external device to the EXP jack on the input side of the Deluxe Big Muff. The position of the MIDS FREQ knob sets the toe position of the expression pedal or maximum frequency for CV. The heel position of the expression pedal equals the MIDS FREQ knobs fully counter-clockwise position. Please see EXP Input below for more on the expression pedal.

MIDS Q Switch (HIGH/LOW)
The Q switch sets the resonance or bandwidth of the MIDS EQ. What this means is in LOW mode the EQ sounds broader or rounder and affects a larger range of frequencies; in HIGH mode the EQ sounds sharper or peakier and affects a narrow range of frequencies.

MIDS FOOTSWITCH / LED
Engages or bypasses the MIDS EQ section. When the white status LED is lit, the MIDS EQ circuit is active and the MIDS LEVEL and FREQ knobs can be used to produce a multitude of different tones.

BYPASS FOOTSWITCH / LED
Toggles between effect mode and true bypass. When the red status LED is lit, the effect is active. When the LED is off, the Deluxe Big Muff Pi is in True Bypass mode.

If you are looking for a fuzz look no further. I've had boutique fuzzes that couldn't cut through the mix in a band. This thing sounds huge and clear as a bell. My main concern was cutting through in a band mix and this does that great. Very happy with this pedal. My fuzz search is over

Seriously - this is the only you'll ever need and it's not that enormous compares to some of the big box deluxe EHX pedals. Add in an expression pedal for the mid frequencies and you have the most versatile ever produced. Purists will snort at it - they're just mad they shelled out $300+ for a soviet and this one sounds as good and can do more. - Fun fact L&M bans the "m-word" aka the name of this pedal so i can't actually use it when writing the review. Really guys?.
