D1 and D2 orientation
In Version 1 of the original pedal D1 and D2 were installed backwards, this was corrected in Version 2.
NOTE: On some germanium diodes the stripe is on the Anode end of the diode instead of the Cathode. This
should be verified with a DMM before installing.
To build Version 1
Install D1 and D2 with cathodes pointing down.
