      Electro-Harmonix Germanium 4 Big Muff Pi Overdrive and Distortion Guitar Effects Pedal (430884)
Availability:  


Dial up that slightly torn speaker sound or dial in total Germanium "Satisfaction."

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.

In addition to a Gain control, the Electro-Harmonix Germanium 4 overdrive lets you control Bias for attack and the circuit volts for that sweet spot found when a battery's voltage dips.

The Gain control adjusts the amount of input signal that is fed to the Electro-Harmonix Germanium 4. The more the knob is rotated the harder the germanium transistor and drive components are hit. The Bias control adjusts the current gain that is sent to the Germanium transistor. It works together with the Voltage control to attain the over all tone. The bias control works specifically with the Germanium transistor. The Volts knob controls the amount of voltage that is applied to the Germanium OD. Set at full, 9V is applied. When set at minimum, 3V is applied. By limiting the voltage a number of interesting saturations can be set up for variations in tone.

A footswitch turns true bypass on or off.

The Electro-Harmonix Germanium 4 runs off of a 9V battery or you can connect a 9VDC adapter capable of delivering at least 100mA to the 9V power jack. The optional 9V power supply from Electro-Harmonix is 9.6DC-200BI (same as used by Boss and Ibanez) 9.6 Volts DC 200mA. The AC power adapter must have a barrel connector with center negative. The battery may be left in or taken out when using an adapter.

Electro-Harmonix Germanium 4 Big Muff Pi Overdrive and Distortion Guitar Effects Pedal Features:

  • True bypass
    Gain control
    Bias knob for putting your sound right at the edge of break up
    Volts knob for reducing battery voltage
    Countless germanium variations at the touch of a knob
    Tough and compact die-cast chassis
    9-volt battery included
    Optional US96DC-200BI power supply available

  • Ooooweee...

    As reviewed by Ryan F. on 10/17/2010

    Wow. This amazing dual unit has so much flexibility. The OD channel can conjure up the lightest dusting of dirt to the full on tone of a modded famous "green" OD. The Distortion side adds a "volt" control which allows for extreme shaping of the timbre of the effect. Lower "volt" settings starve the gain circuit, allowing for the "dying battery" fuzz sound. Higher settings allow the full character of the gain circuit to shine through, adding a nice amount of sustain. Make no mistake, this is not your "classic" Big Muff by any means. This is a killer product with deep amounts of control allowing the user to dial in a plethora of delicious dirty tones from bluesy to modern.

  • SWEEEEET!!!

    As reviewed by MintheGardens on 8/30/2011

    I had been looking for a Germanium based fuzz pedal for that vintage Hendrix/Fuzz Face sound. All I can say is: THIS THING IS DEAD-ON. What's really amazing are the "extra" controls that allow more tonal variations than I can imagine. I have several combination pedals, Danelectro Wasabi, BBE Two-Timer, Marshall Vibra-Trem. I like them because combining two effects into one pedal housing uses much less space on my pedal board. When you consider that the Germanium 4 Big Muff Pi also has an independent Overdrive circuit which could stand alone as a fine pedal and that the two circuits can work alone or together, this is one of the most outstanding values I've ever found. I can't yet evaluate the reliability of this pedal. Electro-Harmonix has a good reputation and the all-metal case seems sturdy enough. If I had one concern, it would be the foot switches. They don't seem as smooth or solid as most of my other pedals. Guess they had to cut corners somewhere. I'll have to see how well they hold up. Believe me, this IS NOT a deal breaker. I got this pedal on a special deal from GC. I had just read a glowing review in a guitar mag and knew I wanted one. GC's special only made it sweeter.

  • Awesome versatile pedal!!

    As reviewed by Cody on 4/18/2011

    I got this pedal a few months ago. It is AWESOME! You can get any thing from just a volume boost the the overdrive side to a harsh fuzz with distortion side and everything in between; Electro-harmonics really hit a solid with this pedal. I would recommended getting a power supply for it though because it will eat a battery very quickly.
