Roight, then. I’ve built many a booster in my time, based around a few different circuits. Usually they go away as quick as I build them, so this was an attempt to build all of them and have one of each at my disposal. Four different boosters in a variety of autumnal colors. How divine.
Left to Right they are: an AMZ Mosfet Boost, AMZ Mini Boost, Balls Boost, and a ZVEX Super Hard-On. The AMZ Mosfet is a pretty standard mosfet boost, which behaves like cranking a tube amp. It provides volume and a little dirt, increasing toward the far end of the dial. The Mini Boost is configured differently and provides a not-so-clean boost. Its basically cranked and then the volume is attenuated at the pedal output so it always gets a *little* overdriven transistor tone. The Balls Boost (formerly blogged as the “Orange Droolius”) is a modified version of the AMZ Mosfet which behaves similarly but adds a touch more filth and some extra bass. The ZVEX SHO is stock.
