Combining four classic germanium transistors, the Germanium Big Muff Pi is the result of a focused modern design dripping with EH 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.

Classic 60's overdrive from genuine germanium transistors. All adjustments for Bias and Volts control are on top of the case and not buried inside of it. The Germanium OD lets you easily dial in that perfect vintage germanium tone. Need proof? Check it out... one try will convince you.

The Electro-Harmonix Germanium 4 Big Muff Pi overdrive and distortiuon pedal is a classic 1960's overdrive based around a hand-selected germanium transistor. To get the best results from the E-H Germanium 4, just set aside some time to practice in a quiet room - just you, your amp, and the Germaium OD. The interaction of each control will reward you with many different flavors of exceptional vintage overdrive

Controls - Distortion Side: The DISTORTION side can be used independently or with the OVERDRIVE side. When both sides are ON, the DISTORTION side precedes the OVERDRIVE side in the signal chain. The DISTORTION utilizes two germanium transistors and is capable of going from clean - to a gritty overdrive - to a full on distortion and beyond. Gain Control: This knob adjusts the amount of preamp gain for the DISTORTION side of the pedal. As you turn the GAIN knob clockwise the distortion and volume will increase dramatically. Bias Control: This knob adjusts the character of the distortion by changing the bias of the signal before it is distorted by the Germanium transistors. Volts Controls: This knob adjusts the amount of voltage supplied to the DISTORTION side only. When the VOLTS knob is turned fully clockwise, the circuit is receiving the full voltage. Turning the VOLTS knob counter-clockwise will simulate a dying battery. As the voltage is lowered, the signal will become more compressed, and start to clip, creating a wide range of sonic textures to work with. Volume Control: This knob controls the output level of the DISTORTION side of the pedal. Fully counter-clockwise will produce no sound. As the VOLUME knob is turned clockwise, the output level will increase to its maximum volume at the full clockwise setting. Tone Control This knob is a single knob tone control. As the TONE knob is turned clockwise, the tone of the OVERDRIVE side will change from a low end emphasis to a high end emphasis.

Electro Harmonix Harmonix Germanium OD Overdrive Kit.

Compatible with Electro-Harmonix GERMANIUM 4 BIG MUFF PI / GERMANIUM OD Guitar Effects pedals.

Classic dual overdrive. The original 1969 plug-in Muff Fuzz had just a touch of overdrive and sounded like a vintage amp with a slightly worn speaker. We paired two of these together in one box to create the Double Muff. Use just one Muff for a hint of milky distortion, or cascade the second Muff for over-the-top overdrive that turns the milk into cream.
