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
transistors and diodes. 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). Use a socket for
IC1, or be super careful.
Snap the small metal tag off the pots so they can be mounted flush in the box.
Positive (anode) legs of the electrolytic caps go to the square pads. C7 and C12 can be laid flat as
shown in the cover image to give you extra clearance in the enclosure.
Negative (cathode) legs of the diodes go to the square pads.
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.
If you aren’t using the optional More Bass switch there’s no need to do anything with the pads for
S1. Ignore them.
There are two sets of pads for LEVEL and DRIVE. This gives you the option to place these controls
further down the enclosure if you’re using the More Bass switch. If not, use the top ones to get the
best control spacing.
More Bass mods
C6 and C13 are extra caps for the More Bass mod. Use one cap spot along with a SPDT ON-ON
switch for a single extra bass setting. If you use C6, the extra bass will be engaged when the
switch is up. Use C13 for extra bass in the down position.
For two extra settings use both cap spots and a SPDT ON-
OFF-ON switch.
Recommended values are 47n for much more bass, 22n for a
little more bass, or use both if you’re going for two settings.
Clipping
D3 is included so you can easily add asymetrical clipping
which changes the nature of the tone. If you want this, just
put a 1N4148 in D3 instead of a jumper.
