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.

After buying this pedal and playing around with it for a bit I have grown to really like it. You can get some really nice Blues and Reggae tones from it and its great for soft music that doesn't require a lot of distortion. I also like to use it as a booster for other distortion pedals. The only thing that disappoints me is the overdrive. Even when I have it cranked all the way up I still feel like I want more. I can't make it scream like a tube screamer. But with that aside it's a pretty solid pedal but I would recommend trying it out yourself before committing to buying it.
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.
so far super happy with it, great for that desert rock sound and vintage vibes, definitely more of an effect than a modern gain, but since i play stoner metal it fits me perfect, i have to use it before a TS9 to keep it nice and tight, going into the clean channel of a 6505+, hit it with a octave pedal and stock gibson 500t and its a glorious happening...a strat does make it a little less loose and records a little more focused... i love mine just hope the germaniums last forever
The pedal is excellent. it covers absolutely every distortion/overdrive you could possibly need(playing rock or similar styles). I highly reccomend it.
This pedal is just terrible When i first plugged it in i was in standard tuning and it sounded fine just a bit fuzzy on the low E but when i went to go play in drop-D everything just sounded muddy The OD was ok but the Distortion is just terrible DO NOT BUY THIS
