Colorsound Overdriver

The Colorsound Overdriver, introduced in 1971 by Sola Sound, is a legendary overdrive and boost pedal that evolved from the earlier Colorsound Power Boost. Designed by Gary Hurst, the Overdriver was created to meet the needs of guitarists seeking a versatile pedal capable of clean boosts, natural overdrive, and even fuzz-like distortion at higher settings. It featured a simplified circuit powered by a single 9V battery (unlike the Power Boost's 18V design) and included a master volume control for better usability. Known for its warm, transparent tone and ability to push tube amplifiers into saturation, the Overdriver became a favorite among guitarists in the 1970s and remains highly collectible today.

Historical Development

• Origins (1971): The Overdriver was introduced as a revision of the Colorsound Power Boost, with reduced power requirements and minor circuit changes. It retained the bright orange enclosure and simple controls for Volume, Treble, Bass, and Gain.
• Design: The pedal was capable of clean boosts at low gain settings and transitioned into rich overdrive or aggressive fuzz at higher levels. Its EQ section allowed for precise tone shaping.
• Legacy: After production ceased in the early 1980s, the Overdriver became a sought-after vintage pedal. Reissues in the 1990s and beyond have kept its legacy alive.

Notable Players

• David Gilmour (Pink Floyd): Used both the Power Boost and Overdriver extensively during the 1970s, particularly on albums like Animals and The Wall. His use of the pedal contributed to its association with soaring lead tones.
• Jeff Beck: Known for employing the Overdriver to achieve his signature dynamic and expressive guitar tones.
• Marc Bolan (T. Rex): Allegedly suggested renaming the Power Boost to "Overdriver" after its introduction to the U.S. market.

Popular Settings

The Colorsound Overdriver's simple controls allow for versatile applications:

• Clean Boost: Set Gain low (9 o'clock) with Volume high for transparent amplification.
• Classic Overdrive: Balance Gain at noon with Treble and Bass adjusted to taste for warm, natural overdrive tones.
• Fuzz-Like Distortion: Max out Gain (3–5 o'clock) for aggressive, saturated fuzz tones.

Legacy

The Colorsound Overdriver is celebrated as one of the earliest overdrive pedals, influencing countless modern designs. Its association with iconic players like David Gilmour and Jeff Beck highlights its versatility across genres like rock, blues, and experimental music. Vintage units are highly prized by collectors for their historical significance and unique tonal character, while reissues ensure that new generations of musicians can experience its timeless sound.
