Boost & Overdrive Pedals

Boost and overdrive pedals were originally designed to push tube amps of the day into full-blown saturation, that just cranking the amps to full volume couldn't achieve - this was before high-gain amps existed and many amps were only capable of achieving crunch tones without help from boost or overdrive pedals.

There are many different 'flavours' of boost and overdrive these days: the more subtle designs add a touch of hair or grit, ideal for bluesy breakup, while others have more punch for a heavier or more harmonically rich sound. Some, such as the famed Klon Centaur, are renowned for their transparency, while others such as the Dallas Rangemaster Treble Booster deliberately boost particular frequencies.
