There are 3 versions of this board (see the build docs last page). Designed by Bruce R.

This board features on-board pots in an X-Wing configuration. So you may mount it either way in an enclosure and have extra space between knobs for easy finger adjustment.

This is a highly moddable board. Additionally, we have included space on the board for custom modifications; if you decide you want to customize the clipping section, add some additional gain to the output buffer stage, etc.

If you come up with your own unique version post a thread under the Show off your pedal section, detailing your preference.
