hardware/stick-preamp - This is a dual channel preamp in the making. I intend to use it with my [Chapman Stick](http://stick.com). You will need the [gEDA programs](http://www.geda-project.org) to view and edit these files. The [PCB editor](http://pcb.geda-project.org) is required to edit the board.
