BIG MUFF PI WITH TONE WICKER

With Enhanced Tone Processing

Congratulations on your purchase of the BIG MUFF Pi with TONE WICKER! The
BMPTW is a battery operated distortion pedal that maintains the legendary Big Muff
Pi sound while offering two powerful and dynamic tonal adjustments that are unique
to any distortion or fuzz product found in the market today. The original BIG MUFF PI
sound is maintained while new tonal variations deliver edgy and aggressive sonic
possibilities.

- THEORY OF OPERATION -

The BIG MUFF Pi with TONE WICKER is an effects pedal designed to deliver all of the
sonic power of the legendary Big Muff Pi while providing user editing capabilities that
are unique to the Tone Wicker design. Wicker mode opens up the high frequency
bandwidth of your distortion sound delivering a top end that is new and exciting. The
Tone switch, when set to OFF, defeats the Big Muff’s Tone knob yielding an
extremely powerful distortion with a fire breathing new Big Muff Pi character.

- CONTROLS -

Sustain knob – As in the original Big Muff Pi, adjusts the amount of sustain and

distortion.

Tone Knob – The Tone knob allows the musician to dial in just the right setting
between deep bass and high treble.

Volume Knob – The volume knob sets the overall output level of the effect.

Wicker Switch – Activate Wicker mode by flipping the Wicker switch up to the ON

position where the high frequency bandwidth is opened up for a bright and clear top
end. Set the Wicker switch to OFF to obtain the classic Big Muff Pi sound.

Tone Switch – The Tone switch allows the user to activate the Tone knob or to
completely bypass the tone circuitry. When the Tone switch is set to ON, the Tone
knob is active, just like a standard Big Muff. When the Tone switch is set to OFF, the
Tone knob and all of its circuitry is bypassed. This setting yields a totally new Muff
distortion with a powerful drive and uncolored gain. High output with attitude. Please
Note: When the Tone switch is set to OFF, turning the Tone knob will produce no

change to your sound. In addition, it is normal for the output volume of your Big Muff
Pi with Tone Wicker to increase when moving the Tone switch from ON to OFF.

Status LED - When the LED is lit; the BMPTW effect is active. When the LED is off,
the BMPTW is in True Bypass mode. The Footswitch toggles between effect and
bypass modes.

INPUT Jack – This ¼” jack is the audio input to the BMPTW. The input impedance
presented at this jack is 130 kΩ.

OUTPUT Jack – This ¼” jack is the audio output from the BMPTW. When the
BMPTW is in Bypass mode, the OUTPUT jack is connected directly to the INPUT jack.

9V Power Jack – The Big Muff with Tone Wicker is battery powered. You may use
an external AC Adapter power supply instead of the battery. Connect the AC
Adapter’s plug to the 9V Power Jack at the top of the BMPTW. The power jack’s
polarity is center negative. The BMPTW requires a clean 9VDC power supply at 50mA.

We recommend the Electro-Harmonix US96DC-200BI power supply.
