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.  Huge overdrive tones available with the gain cranked as well as a healthy volume boost should you need it.  Available in 1590B sized enclosure only, mini ones are discontinued.  Runs on a standard 2.1mm boss style 9v power adapter.  Current draw ~7mA.  $175CAD shipped.
