DO NOT PLACE D2 OR C8
IN THE POSITIONS ON
THE PCB.

IGNORE THESE PADS. ISTAKES WERE ADE. HEADS ROLLED.

Notes
C8 - power filtering capacitor.
This was added on the underside of the
PCB, but the anode was connected to
the wrong net, so don’t add it in this
position.
It can be added to one of the sets of V
and G pads in your build, depending on
which wiring method you’re using.
If you have a side-mounted DC socket
and you’re using the V and G pads on the
footswitch daughterboard, add C5 to the
V and G pads on the top edge of your
main circuit board, + leg to V pad. Check
the positioning of the board, pot and DC
socket to see how it’ll best fit within the
space in the enclosure. >>>
If you have a top-mounted DC socket
and you’re using the V and G pads on the
the top edge of the main circuit board,
add C5 to the V and G pads on the left
side of the footswitch daugherboard,
+ leg to V pad. It should mount on the
underside of the PCB so it’ll sit next to
the body of the footswitch when
mounted. >>>
D2 - power polarity protection.
Same deal as above, we made a mistake.
This is an entirely optional part. If you
want to add it the easiest way is to
connect it to the legs of C8. Cathode
(striped leg) to + leg of C8, anode to - leg.
NOTE: PCB shown below is the EPic Boost,
but it’s the same deal.

Set up...
Not a lot to do here.
Simply adjust T1 until you get your desired level of sustain without distortion.
