Colordriver

The Tru-Fi 9V Colordriver Overdriver is a hand-built recreation of the legendary 1971 Colorsound Overdriver, the 9-volt successor to the original 18V Power Boost. Favored by icons like David Gilmour, Jeff Beck, and Marc Bolan, the circuit became famous for its huge boost and rich, powerful overdrive. Loaded with authentic BC109 transistors, this faithful replica captures the explosive gain, dynamic response, and unmistakable character of the original. Run it straight after your guitar to drive a fuzz, push your amp into natural breakup, or crank the gain for bold, sustaining overdrive. Roll the gain back and raise the master to achieve a loud, clean boost with added fullness and clarity. Housed in a compact enclosure and powered by 9V battery or standard negative-tip supply, it delivers vintage tone with modern practicality.
