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.
