KO Sound Power Boost
Based on the Colorsound Power Boost. As used by David Gilmour, Jeff Beck, etc. Very versatile for such a small package with four knobs controlling bass treble gain and volume. Has an internal voltage doubler so the circuit gets an 18v supply just like the originals. Three BC184L transistors provide the period correct tone. Huge overdrive tones available with the gain cranked as well as a healthy volume boost should you need it. Also available in the 'overdriver' version that is almost the same circuit minus the voltage doubler for lower headroom and more overdrive. Runs on a standard 2.1mm boss style 9v power adapter. Current draw ~7mA. $175CAD shipped.
