The power and signal pads on the PCB conform
to the FuzzDog Direct Connection format, so can
be paired with the appropriate daughterboard for
quick and easy offboard wiring. Check the
separate daughterboard document for details.
Be very careful when soldering the diodes and
transistors. They’re very sensitive to heat. You
should use some kind of heat sink (crocodile clip
or reverse action tweezers) on each leg as you
solder them. Keep exposure to heat to a
minimum (under 2 seconds).
Snap the small metal tag off the pots so they can
be mounted flush in the box.
You should solder all other board-mounted
components before you solder the pots. Once
they’re in place you’ll have no access to much of
the board. Make sure your pots all line up nicely.
The best way to do that is to solder
a single pin of each pot in place then melt and
adjust if necessary before soldering in the other
two pins. If your pots don’t have protective
plastic jackets ensure you leave a decent gap
between the pot body and the PCB otherwise
you risk shorting out the circuit.
There are extra pads on trimmers to allow
different package formats to be used. Pads are
connected via PCB traces as shown above, so
just fit your trimmer into whichever holes it fits
naturally into. As long as you have one pin each
in the top, middle and bottom sections.
No jumpers are required.
There’s no set voltage to aim for to bias this up.
Adjust it until it sounds good to you.
