The Four Banger is a booster pedal for electric guitar. The pedal contains four different booster circuits that each have their own separate boost volume knobs and their own on/off switch; this enables more than one boost to be used simultaneously. The different boosters are as follows: a Germanium Treble boost in the style of the classic Rangemaster, a super-clean Opamp boost (original design), a MOSFET boost (in the style of a certain popular boost with gain control that crackles), and a JFET mu-amp boost based on the popular DIY MiniBooster designed by Jack Orman. They are stacked in series, which enables different combinations of overdrive and fuzz.
I absolutely ripped @$$ last night at that gig, especially when I plugged in my trusty old four banger.

Whenever you take a dump and you poop along with make a fart noise that is a result of air in the stomach, possibly heartburn. This fart will last more than ten seconds and is rather loud for a fart. It will sound like a 4 cylinder car shifting gears in fart form. It is possible that you can poop loosely too.
A four banger fart/dump sounds like a four cylinder car shifting gears and is very similar to shotgun pooping, but you do not feel a rush to go to the toilet. This poop will sometimes come out with force. The farting/poop sounds are more of an explaination for this. Four banger/fart dump, shotgun poop ( if there is a pause between the rushed dump as in diaherrea.
