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.
Be very careful when soldering the
ED, 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). You should use a
socket for IC1 or be ultra careful
when soldering.
The cathode (striped end) of the diodes go
into the square pads. The anode (long leg)
of electrolytic capacitors go into the square
pads. C12 can be bent over the adjacent
resistors to save on height (see pic on first
page), giving more clearance when
mounting in the enclosure.
Snap the small metal tag off the pots so
they can be mounted flush in the enclosure.
If you’re using a footswitch daugherboard
don’t bother soldering R ED. You’ll use that
on the daughterboard instead. What does
C R mean? Current imiting Resistor. It’s
what stops your ED from popping. You can
use anything from 1K-4K7 here, depending
how bright you want your ED to be. ower
value = brighter.
Pots mount on the back side of the board.
You can use vertical-mount pots or just wire
up ‘normal’ ones. It’s a good idea to place
the pots in their holes in the enclosure
when you’re soldering them in place on the
PCB. That way you know they’re going to
line up ok. Best way to do it is to solder a
single pin of each pot in place, then do a
visual check to see that they’re sitting at the
same height. If not, melt the joints and
readjust any that are off.
POT POSITIONS
You’ll notice there are two lots of pads for
EVE and DRIVE. The lower set were
added so those pots could be offset if using
the switch S1 for a Tube Screamer More
Bass mod. For correct postitioning you
should use the upper pads on your build.
The cover image doesn’t show C7 in place.
The pretty photo was taken before we
realised it was missing. Make sure you
include it.
