Treble booster pedal
From Wikipedia, the free encyclopedia
A treble booster pedal is an effects unit used by guitarists to alter the sound of their guitars.
Popularized by legendary guitarists such as Brian May of Queen and Eric Clapton, treble booster pedals have been used to overdrive tube amplifiers, such as Vox AC30s, in order to create a cleanly-driven type of distortion. There have been many different types of treble boosters made. One of the most important early examples, though not a pedal, was the Dallas Rangemaster, which was used widely in the late 60s and early 70s. Though hard to find today, its sound is still sought after, and many clones exist. The key to the Rangemaster's sound, and indeed most treble boosters, is a Germanium Transistor. One can hear the Rangemaster in many Queen songs, a good example would be Procession off of Queen's second album, Queen II. Also, most of Eric Clapton's guitar work with Cream used the Rangemaster or other Treble Booster.
Current versions of the effect include the Crispy Cream Treble Booster, the Brian May Fryer Treble Booster and the Java Boost by Keely Electronics.
