Germanium 4 Big Muff Pi

DESCRIPTION

Combining four classic germanium transistors, the EHX Germanium 4 Big Muff Pi is the result of a focused modern design dripping with EHX analog heritage. An independent overdrive and distortion each have their own sets of two germanium transistors as well as independent controls. The ability to stack and use both the overdrive and distortion together delivers the power of a four germanium transistor circuit with ultimate control flexibility.

  • Individual overdrive and distortion with the ability to stack them together
  • 4 individual Germanium Transistors
  • Each mode of drive mode uses its own 2 germanium stack
  • Overdrive and distortion can be stacked utilizing four germanium transistors
  • Bias and tone control define the tonality in overdrive
  • Volts and Bias define the way the distortion will react
  • Starving battery sound through volts control adds character
  • 9V battery included

GAIN CONTROL
Adjusts the amount of gain.
BIAS CONTROL
Adjusts the character of the distortion by changing the bias of the signal in the preamp section of the overdrive circuit.
TONE CONTROL
Single knob tone control.
GAIN CONTROL
Adjusts the amount of preamp gain for the DISTORTION side of the pedal.
BIAS CONTROL
Adjusts the character of the distortion by changing the bias of the signal before it is distorted by the Germanium transistors.
VOLTS CONTROL
Adjusts the amount of voltage supplied to the DISTORTION side only.
VOLUME CONTROL
Controls the output level of the OVERDRIVE side of the pedal.
VOLUME CONTROL
Controls the output level of the DISTORTION side of the pedal.
STATUS LED AND FOOTSWITCH (OVERDRIVE)
When this LED is lit; the GERMANIUM4 BIG MUFF PI OVERDRIVE effect is active. The footswitch engages/disengages this effect.
STATUS LED and FOOTSWITCH (DISTORTION)
When this LED is lit; the GERMANIUM4 BIG MUFF PI DISTORTION effect is active. The footswitch engages/disengages this effect.
INPUT JACK
Connect your instrument to the input jack.
OUTPUT JACK
Connect this jack to your amplifier.

“Separate overdrive and distortion for the price of a single stompbox, and with enough control to create a wide-ranging dirty tone.”
